Answer:

Do the order of operations after you plug everything in. If that doesn't help do a proof.

A rectangular prism has a volume of 572 cubic inches. The prism is 4 inches long and 13 inches wide. What is the height of the p

Leya [2.2K]

Answer:

Height of rectangular prism = 11 inches

Step-by-step explanation:

Given that:

Volume of rectangular prism = 572 cubic inches

Length of prism = 4 inches

Width of prism = 13 inches

Volume of prism = Length * Width * Height

572 = 4 * 13 * h

572 = 52h

52h = 572

Dividing both sides by 52

$\frac{52h}{52}=\frac{572}{52}\\h=11$

Hence,

Height of rectangular prism = 11 inches
