As a contrast between the old and the modern and between the large and the small, consider the following: In old rural England 1 hide (between 100 and 120 acres) was the area of land needed to sustain one family with a single plough for one year. (An area of 1 acre is equal to 4047 m2.) Also, 1 wapentake was the area of land needed by 100 such families. In quantum physics, the cross-sectional area of a nucleus (defined in terms of the chance of a particle hitting and being absorbed by it) is measured in units of barns, where 1 barn is 1 × 10-28 m2.

- Is the following statement reasonable? The area of a dorm room is 49 m2.arrow_forwardFigure P1.6 shows a frustum of a cone. Match each of the three expressions (a) (r1 + r2)[h2 + (r2 r1)2]1/2, (b) 2(r1 + r2), and (c) h(r12 + r1r2 + r22)/3 with the quantity it describes: (d) the total circumference of the flat circular faces, (e) the volume, or (f) the area of the curved surface. Figure P1.6arrow_forwardIn the Bible, Noah is instructed to build an ark 300 cubits long, 50 cubits wide and 30 cubits high. (A cubit was a unit of length based on the length of the forearm and equal to half of a yard.) What would the dimensions of the ark be in meters? What would its volume be in cubic meters? (Assume that the ark was rectangular.)arrow_forward
- A contractor wants to install ceramic tile in a kitchen of length 9.13 m and width 6.2 m. What is the area of the room (in m2)? Express your answer using the proper number of significant figures.arrow_forwardImagine a library : there are shelves 8 m high, filled with books on both sides, if the width of the shelves is 60 cm and the distance between the shelves (corridor) is 1.5 m. So first, calculate how many shelves to occupy an area of 3500 m2, how many books are on one shelf, and finally how many books are in total.... Information about the dimension of each book and also the length of the book shelves or other. Assume yourself Answer with the step thank U... Please no reject this question is complete im needed in 30-40 minutes thank uarrow_forwardCalculate the approximate number of board feet (one board foot is defined as a volume of 1 in x 1 ft x 1 ft) of lumber that would be available in a log that has a diameter of 26 cm and a length of 2.4 m. Assume the log is a right cylinder and that the saw mill must make the log into a rectangular prism before cutting it into boards.arrow_forward
- a) A pyramid has a height of 484 ft and its base covers an area of 11.0 acres (see figure below). The volume of a pyramid is given by the expression V = where B is the area of the base and h is the height. Find the volume of this pyramid in cubic meters. (1 acre = 43,560 ft2) 2.19*10**6 m3 b) What If? If the height of the pyramid were increased to 519 ft and the height to base area ratio of the pyramid were kept constant, by what percentage would the volume of th pyramid increase? X %arrow_forwardPaperweight I bought a pack of 100 rectangular index cards. Each card measured 15 by 10 cm. The pack said :Paper Density = 200 GSM (grams per square meter). This means that a square meter of those cards weighs 200 g. A) All of the cards in the pack are place flat on a table without overlap. In square meters, what is the total area of the table covered by the cards? B) Each pack of cards is wrapped in a sheet of 50 GSM paper with an area of 800cm squared. I have a number of packs and wish to store them on a shelf that cannot hold more than 10 kg. What is the largest whole number of wrapped packs that can be stored? C) The total weight of 500 identical sheets of paper is 2.4kg. If each sheet measures 30cm by 20cm, what is its paper density in GSM? D) A business card measures 55mm by 90mm. Its paper density is 300 GSM. Fins its exact weight in grams.arrow_forwardThe length and width of a rectangular room are measured to be 3.885 ± 0.0065 m and 3.2 ± 0.0045 m. In this problem you can approximate the error on a product or quotient of quantities by the sum of the percent error on each quantity.Calculate the floor area of the room in square meters.arrow_forward
