What is the surface area of a rectangular prism with length 8 cm, width 5 cm, and height 10 cm?

Answer explanation

To find the surface area of a rectangular prism, use the formula 2lw + 2lh + 2wh. Plugging in the values, we get 2(8*5) + 2(8*10) + 2(5*10) = 260 cm^2.

A rectangular prism has dimensions 8 cm by 5 cm by 2 cm. What is the total surface area?

• 148 cm²

• 132 cm²

• 76 cm²

• 92 cm²

Answer explanation

To find the total surface area of a rectangular prism, use the formula 2lw + 2lh + 2wh. Substituting the given dimensions, we get 2(8*5) + 2(8*2) + 2(5*2) = 132 cm².

• 8 cm

• 10 cm

• 11 cm

• 14 cm

Answer explanation

To find the height of the rectangular prism, divide the surface area by the product of length and width: 448 / (8 * 7) = 8 cm. Therefore, the height is 8 cm.
