KS2 Primary Maths Age 9-13 - Volume and Surface Area: - Explained

The video tutorial explains how to calculate the volume and surface area of a shape made from centimeter cubes. It begins with an introduction to the shape, followed by a detailed explanation of calculating its volume. The tutorial then covers the surface area calculation in two parts, considering the shape as two separate sections before joining them. The final section discusses the overall surface area and the distribution of marks for the problem.

What is the volume of a shape made from six 1 centimeter cubes?

• 6 cubic centimeters

• 3 cubic centimeters

• 12 cubic centimeters

• 18 cubic centimeters

How is the surface area of three joined cubes calculated?

• By multiplying the number of cubes by 2

• By calculating the area of all visible faces

• By subtracting the hidden faces

• By adding the volume of each cube

What is the total surface area of two separate shapes made of three cubes each?

• 42 square centimeters

• 56 square centimeters

• 28 square centimeters

• 14 square centimeters

What is the final surface area of the shape after accounting for joined faces?

• 30 square centimeters

• 28 square centimeters

• 24 square centimeters

• 26 square centimeters

Which method can be used as an alternative to calculate the surface area?

• Subtracting the volume from the surface area

• Adding up all visible squares on the diagram

• Counting the number of cubes

• Multiplying the length by width
