Find the surface area of the figure to the nearest whole number.

Question

Answer 1

Hello. To find the surface area you will need to find the area of the 3 unique sides of this rectangular prism. The multiply each of these unique areas by 2 and add them all up. Lastly, we will round to the nearest whole #.

Remember Area = Length x width

There is the Front (and back) facing side which is 4.5ft x 10 ft = 45 ft²

There are the sides which are 2.25 ft x 10ft = 22.5 ft²

There are the Top and Bottom which are 2.25 ft x 4.5 ft = 10.125 ft²

double each of these areas:

= 90 ft²

= 45 ft²

+ = 20.25 ft²

155.25 ft² _{rounded =} 155 ft²

I hope this helps!
