Question

I really need help, the problem is attached. 20 points!

Answer 1

length = 15 meters

Explanation:

Volume of a pyramid is:

V = l*w (h/3)

We know that; Volume is 40, Width is 2, and Height is 4, therefore;

40 = l*2 (4/3)

40 = 2l (4/3)

(3/4) * 40 = 2L

30 = 2L

30/2 = L

15 = L

therefore the length = 15 meters

Hope this helps!

Answer 2

`volume \: of \: the \: rectriangular \: prism = ( (1)/(2) * base * 4) * 2 \\ 4 * base = 40 \\ base = 10m`
