Unitary Method
The word “unitary” comes from the word “unit”, which means a single and complete entity. In this method, we find the value of a unit product from the given number of products, and then we solve for the other number of products.
Speed, Time, and Distance
Imagine you and 3 of your friends are planning to go to the playground at 6 in the evening. Your house is one mile away from the playground and one of your friends named Jim must start at 5 pm to reach the playground by walk. The other two friends are 3 …
Profit and Loss
The amount earned or lost on the sale of one or more items is referred to as the profit or loss on that item.
Units and Measurements
Measurements and comparisons are the foundation of science and engineering. We, therefore, need rules that tell us how things are measured and compared. For these measurements and comparisons, we perform certain experiments, and we will need the experime…

Question
number 33 only (9.1)
**Exercises 31-33** The image appears to show a three-dimensional geometric figure, specifically a cube. The cube has several of its edges labeled as follows: - Vertex A is identified at the top front-left corner of the cube. - Vertex B is identified at the bottom front-left corner. - Vertex C is identified at the bottom front-right corner. - Vertex D is identified at the top back-left corner. The cube is drawn with dashed lines representing the edges that are not visible from the current perspective, indicating a three-dimensional object.

### Mathematics Exercises **32.** Use the formulas and drawings in Exercise 31 to find (a) the total area and (b) the volume of a cube with edges of length 5.3 ft each. --- **33.** When the length of each edge of a cube is increased by 1 cm, the volume is increased by 61 cm³. What is the length of each edge of the original cube? --- **34.** The numerical value of the volume of a cube equals the numerical value of its total surface area. What is the length of each edge of the cube? --- **35.** The sum of the lengths of all edges of a cube is 60 cm. Find the volume \( V \) and the surface area \( S \) of the cube. --- **36.** A concrete pad 4 in. thick is to have a length of 36 ft and a width of 30 ft. How many cubic yards of concrete must be poured? --- These exercises are designed to help students apply mathematical formulas related to the properties of cubes in practical contexts. Students will practice calculating total area, volume, and relationships between the dimensions of cubes, reinforcing their understanding of geometry and measurement. **Note:** For Exercise 32, refer to Exercise 31 for specific formulas and drawing references which are necessary to solve the problem. **Graph/Diagram Explanation:** While the problem set currently does not include any graphs or diagrams, it is important for students to visualize geometric problems. Diagrams showing cubes and their properties, such as edge length, volume, and surface area, can greatly aid in understanding.
