Answer 2

The surface area of right rectangular prism is 150 square centimeter

Solution:

The surface area of a right rectangular prism can be found by finding the sum of the area of each of the faces of the prism

To find: surface area of right rectangular prism

Given that,

length = 4 cm

width = 9 cm

height = 3 cm

The formula for surface area of rectangular prism is given as:

A = 2(lw + hl + hw)

Where, "l" is the length and "h" is the height and "w" is the width

Substituting the given values, we get'

`A = 2(4 * 9 + 3 * 4 + 3 * 9)\\\\A = 2(36+12+27)\\\\A = 2 * 75\\\\A = 150`

Thus surface area of right rectangular prism is 150 square centimeter
