Surface area of right rectangular prisms quick check use the formula for the surface area of a right rectangular prism to find the surface area of a space with the following measurements length equals 4.5 CM with equals 3.5 CM height equals 2.5 cm answers 71.5 CM power to 63 cm power to 735.75 CM power to 10.5 CM power to
To find the surface area of a right rectangular prism, you need to calculate the area of each of its six faces and then sum them up.
The formula for the surface area of a right rectangular prism is:
Surface Area = 2lw + 2lh + 2wh
where l is the length, w is the width, and h is the height.
Given measurements:
Length (l) = 4.5 cm
Width (w) = 3.5 cm
Height (h) = 2.5 cm
Substituting these values into the formula:
Surface Area = 2(4.5)(3.5) + 2(4.5)(2.5) + 2(3.5)(2.5)
= 31.5 + 22.5 + 17.5
= 71.5
Therefore, the surface area of the given right rectangular prism is 71.5 cm².
