What is the formula for the volume of a cube?

Back

Volume = edge³.

Front

How do you calculate the surface area of a cube?

Back

Surface Area = 6 × edge².

Front

What is the formula for the volume of a square pyramid?

Back

Volume = (1/3) × base area × height.

Front

How do you find the total surface area of a square pyramid?

Back

Total Surface Area = base area + lateral surface area.

Front

What is the lateral surface area of a pyramid?

Back

Lateral Surface Area = (1/2) × perimeter of base × slant height.

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.

Front

How do you calculate the area of a rectangle?
