Question

A rectangular prism has dimensions x units, 2x units, and x 8 units. which expression represents the surface area of the prism? 8x 16 square units 16x 32 square units 10x2 48x square units 2x3 16x2 square units

Answer 1

The rectangular prism with dimensions x units, 2x units, and x- 8 units has a surface area of 10x^2 - 48x square units

Volume of a rectangular prism

The formula for calculating the suface area of rectangular prism is expressed as:

A =2()

lw + wh + lh

where:

• l is the length
• w is the width
• h is the height

Given the following parameters

l = x units

w = 2x units

h = x -  8 units

Substitute

S = 2(2x^2 + x^2 - 8x + 2x^2 - 16x)

S = 2(5x^2-24x)

S= 10x^2 - 48x square units

Hence the rectangular prism with dimensions x units, 2x units, and x- 8 units has a surface area of 10x^2 - 48x square units
