of you have a wire with density 7800 kgm-3 and mass 16 g and length 250 cm , how can we find the area of the wire ( cross section )

Been having trouble with this one

QUESTION 1 The linear mass density (A) of a rod of length L is given by A = a+ Bx2 where a and B are constants and x is the distance from one end. What is the total mass of this rod? a + BL2 aL + (BL³)/ 3 (a+ Bx2)L O al + (BL2)/ 2

Measures ID Fixed main scale mu Measures depth Moveable auxiliary scale Measures OD PART A: Determining VOLUME and (mass) DENSITY of three samples using VERNIER CALIPER only 1. Determine the zero reading of the Vernier caliper. This is the reading when the jaws of the instrument are in contact with each other. Be sure that the jaws are clean so no grit or other foreign matter gets between them and prevents true contact. Record the zero reading to 0.001 cm. 2. Measure the length and diameter of the samples. These measurements are made by closing the jaws of the caliper on the length or diameter of the object being measured and reading the position where the zero line of the Vernier falls on the main scale. The fractional part of a main-scale division is obtained by noting which line on the Vernier coincides with a line of the main scale. Record the reading in centimeters and read to 0.001 cm.

2. Calculate the dimensions of the economic channel in the form of a trapezoid with a slope of 1. (horizontal), 2. (vertical) to pass a discharge of 40 m^3/s with an average speed of 0.8 m/s. What is the slope of the bottom of the channel if the Chezy coefficient C= 50 m^1/2/det
