Question

A rectangular prism has a length 5 inches, width 3 inches, and height 7 inches. What is the volume of the prism?

Answer 1

Step-by-step explanation:

volume=width×height×length

v=3×7×5

v=105 inches

Answer 2

In rectangular surface

length (l) = 5 inch

width (w) = 3 inch

now,

CSA of prism = lw

= 5×3

= 15 inch²

Again

height (h) = 7 inch

Vol. of Prism = CSA × height

= 15×7

= 105 inch³
