Front

If a rectangular box has a length of 4 inches, width of 3 inches, and height of 2 inches, what is its surface area?

Back

Surface Area = 2(lw + lh + wh) = 2(4*3 + 4*2 + 3*2) = 2(12 + 8 + 6) = 2(26) = 52 square inches.

Front

What is the surface area of a cube with a side length of 5 cm?

Back

Surface Area = 6s² = 6(5)² = 6(25) = 150 cm².

Front

How do you calculate the surface area of a cylinder?

Back

Surface Area = 2πr(h + r), where r is the radius and h is the height.

Front

What is the surface area of a rectangular prism with dimensions 2 ft, 3 ft, and 4 ft?

Back

Surface Area = 2(lw + lh + wh) = 2(2*3 + 2*4 + 3*4) = 2(6 + 8 + 12) = 2(26) = 52 ft².

Front

What is the difference between area and surface area?

Back
