Question

Part 2 -Find the error(s) and solve the problem correctly.Find the volume of the given pyramid. Measurements are in feet.

Answer 1

There are 2 errors here.

1.The height used in finding the volume is the perpendicular height, not the slant height

2. The multiplication was wrong.

CORRECT SOLUTION

`V=(1)/(2)Bh`
`B=20*20=400ft^2`

Using pythagoras theorem, we find h to be;

`\begin{gathered} h=√(26^2-10^2) \\ h=24cm \end{gathered}`
`V=(1)/(3)*400*24=3200ft^3`
