Surface Area Review

Front

What is the formula for the total surface area of a prism?

Back

Total Surface Area = 2 * Base Area + Lateral Surface Area.

Front

What is the base shape of a triangular prism?

Back

The base shape of a triangular prism is a triangle.

Front

Calculate the total surface area of a rectangular prism with length 5m, width 3m, and height 4m.

Back

Total Surface Area = 2(5*3 + 5*4 + 3*4) = 2(15 + 20 + 12) = 2(47) = 94m².

Front

What is the surface area of a cylinder with radius 3cm and height 5cm?

Back

Surface Area = 2πr(h + r) = 2π(3)(5 + 3) = 48π cm².

Front

What is the surface area of a cube with side length 4cm?

Back

Surface Area = 6 * side² = 6 * (4)² = 96 cm².

Front

What is the lateral surface area of a cylinder?

Back

Lateral Surface Area = 2πrh.

Front

How do you find the area of a triangle?

Back

Area = 1/2 * base * height.

Front

What is the surface area of a sphere with radius 7cm?

Back

Surface Area = 4πr² = 4π(7)² = 196π cm².

Front

What is the total surface area of a cone with radius 3cm and height 4cm?

Back

Total Surface Area = πr(r + l), where l = √(r² + h²) = √(3² + 4²) = 5. Total Surface Area = π(3)(3 + 5) = 24π cm².

Front

What is the formula for the surface area of a rectangular prism?

Back

Surface Area = 2(lw + lh + wh), where l = length, w = width, h = height.
