What is the surface area of the rectangular prism? (1 point) square inches
(10in, 9in, 3in)
The surface area of a rectangular prism can be calculated using the formula: 2lw + 2lh + 2wh, where l is the length, w is the width, and h is the height.
Given:
Length = 10 inches
Width = 9 inches
Height = 3 inches
Plugging these values into the formula:
Surface Area = 2(10x9) + 2(10x3) + 2(9x3)
Surface Area = 2(90) + 2(30) + 2(27)
Surface Area = 180 + 60 + 54
Surface Area = 294 square inches
Therefore, the surface area of the rectangular prism is 294 square inches.
