What is the surface area of a rectangular prism whose dimensions are 3 3/4 dm×4 1/2 dm× 5 dm in square decimeters

Answer 1

To find the surface area of a rectangular prism, you need to calculate the area of each of the six faces and then add them up.

The formula to find the surface area of a rectangular prism is: 2lw + 2lh + 2wh, where l is length, w is width, and h is height.

Given dimensions:
Length (l) = 3 3/4 dm = 3.75 dm
Width (w) = 4 1/2 dm = 4.5 dm
Height (h) = 5 dm

Using the formula:
Surface Area = 2lw + 2lh + 2wh
Surface Area = 2 * 3.75 * 4.5 + 2 * 3.75 * 5 + 2 * 4.5 * 5
Surface Area = 33.75 + 37.5 + 45
Surface Area = 116.25

Therefore, the surface area of the rectangular prism is 116.25 square decimeters.

Answer 2

can you put it in fraction

Answer 3

To convert the decimal surface area to a fraction, we can express it as a fraction over 1:

116.25 = 116 25/100 = 116 1/4

Therefore, the surface area of the rectangular prism is 116 1/4 square decimeters.
