Question

a rectangular prism has 711.68 cubic feet and its 4 feet long and 12.8 feet wide what's the height

Answer 1

Given:

$w = 12.8 \: ft$

$l = 4 \: ft$

$v = 711.68 \: {ft}^{3}$

To find:

The height of the given rectangular prism.

Solution:

$v = lbh$

$12.8 \times 4 \times h = 711.68 \: {ft}^{3}$

$51.2 \times h = 711.68 \: {ft}^{3}$

$h = \frac{711.68}{51.2}$

$h = 13.9 \: ft$

Therefore, the height of the given rectangular prism is 13.9 feets.
