## Steps to Find Area & Volume of a Rectangular Prism

The step by step workout for how to find what is the volume and surface area of a rectangular prism.__workout :__

step 1 Address the formula, input parameters and values

Length = 5 in

Width = 3 in

Height = 6 in

step 2 Apply length, width and height values in below volume formula

Volume V = lwh

= 5 x 3 x 6 in³

Volume V = 90 in³

step 3 Apply length, width and height values in below surface area formula

Surface area A = 2 (lw + lh + wh)

= 2 ((5 x 3) + (5 x 6) + (3 x 6)) in²

= 2 (15 + 30 + 18) in²

= 2 x 63 in²

Surface area A = 126 in²

## Definition & Formulas

**Prism** is a three dimensional plane or geometric shape having both the ends very similar, parallel and equal line lengths. A square or rectangle base with the sides of squares called the rectangle prism, whereas a triangle face with rectangle base called the triangle prism.
