maxonik [38]

Answer:

Part 1) $LA=220\ ft^2$

Part 2) $SA=280.5\ ft^2$

L = 220 ft2 ; S = 280.5 ft2

Step-by-step explanation:

<u><em>The correct question is </em></u>

Find the lateral area and surface area of a rectangular prism. The base is a square 5.5 ft by 5.5 ft, and the height is 10 ft

Part 1) Find the lateral area

The lateral area of a rectangular prism is equal to

$LA=Ph$

where

P is the perimeter of the base

h is the height of the prism

we have

$P=4(5.5)=22\ ft$ ---> the perimeter of a square

$h=10\ ft$ ---> is given

substitute

$LA=22(10)=220\ ft^2$

Part 2) Find the surface area

The surface area of a rectangular prism is equal to

$SA=2B+LA$

where

LA is the lateral area

B is the area of the base

we have

$LA=220\ ft^2$

$B=5.5^2=30.25\ ft^2$ ----> area of a square

substitute

$SA=2(30.25)+220=280.5\ ft^2$
