Volume and Surface Area Review 8th Grade

Front

What is the formula for calculating the surface area of a rectangle?

Back

Surface Area = Length × Width

Front

What is the formula for calculating the volume of a cylinder?

Back

Volume = πr²h

Front

How do you calculate the total surface area of a rectangular prism?

Back

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

Front

What is the volume of a cube with side length 's'?

Back

Volume = s³

Front

What is the formula for the volume of a cone?

Back

Volume = (1/3)πr²h

Front

What is the formula for the surface area of a cylinder?

Back

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

Front

What is the difference between surface area and volume?

Back

Surface area measures the total area of the surface of a 3D object, while volume measures the amount of space inside the object.

Front

If a cylinder has a radius of 3 cm and a height of 5 cm, what is its volume?

Back

Volume = π(3)²(5) = 45π cm³ (approximately 141.37 cm³).

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

Back

Surface Area = 6s² = 6(4)² = 96 m².
