Find the lateral area and surface area of the solid. Use the 2.5 by 2.5 square as the base. Round to the nearest tenth if necess
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
