Apply the technique of using nets. What is the surface area of the rectangle prism whose dimensions measure 7” x 3” x 11”

Answer 1

To find the surface area of a rectangle prism (also known as a rectangular solid), we can use the formula:
Surface Area = 2lw + 2lh + 2wh
where l, w, and h are the length, width, and height of the prism respectively.

Given that the dimensions of the rectangle prism are 7” x 3” x 11”, we can plug these values into the formula:
Surface Area = 2(7)(3) + 2(7)(11) + 2(3)(11)
Surface Area = 2(21) + 2(77) + 2(33)
Surface Area = 42 + 154 + 66
Surface Area = 262 square inches

Therefore, the surface area of the rectangle prism is 262 square inches.
