Surface Area of Right Rectangular Prisms Quick Check 1 of 51 of 5 Items Question Use the formula for the surface area of a right rectangular prism to find the surface area of a shape with the following measurements: length = 4.5 cm, width = 3.5 cm, and height = 2.5 cm.(1 point) Responses 10.5 cm2 10.5 cm squared 71.5 cm2 71.5 cm squared 63 cm2 63 cm squared 35.75 cm2
The formula for the surface area of a right rectangular prism is:
SA = 2lw + 2lh + 2wh
Plugging in the given measurements:
SA = 2(4.5)(3.5) + 2(4.5)(2.5) + 2(3.5)(2.5)
SA = 31.5 + 22.5 + 17.5
SA = 71.5
So, the surface area of the shape is 71.5 cm².
