Question

A rectangular prism is 5 inches wide and 7 inches high. Its volume is 70 cubic inches. What is the length of the rectangular prism?

Answer 1

Answer: The length of the rectangular prism is 2 inches long

Step-by-step explanation:

The volume of a rectangular prims is its height multiplied by its width multiplied by its length

h×w×l=70

We can sub in the known values of width and height and simplify

5×7×l=70

35l=70

Finally, divide both sides by 35 to isolate l

$\frac{35l}{35} =\frac{70}{35} \\l=2$
