Geometry and Measurements: Lateral Area and the Total Area of a Cuboid

The video tutorial explains the concept of cuboids, which are common in everyday items like cereal boxes and stoves. It covers the basic properties of cuboids, including their edges, vertices, and faces. The tutorial then details how to calculate the lateral area of cuboids, distinguishing between those with rectangular and squared bases. Finally, it explains how to determine the total area of cuboids, considering whether they have lids or not.

How many edges does a cuboid have?

• 14

• 12

• 8

• 6

What is the formula to find the perimeter of a rectangular base of a cuboid?

• Length plus width

• Length times width

• Length plus width times 2

• Length times width times 2

For a cuboid with a square base, how do you calculate the perimeter of the base?

• Multiply the length of one side by 2

• Multiply the length of one side by 3

• Multiply the length of one side by 4

• Multiply the length of one side by 5

How is the total area of a cuboid with a lid calculated?

• Add the lateral area to the area of one base

• Multiply the lateral area by the area of two bases

• Add the lateral area to the area of two bases

• Multiply the lateral area by the area of one base

What is the total area of a cuboid without a lid?

• Lateral area plus the area of two bases

• Lateral area plus the area of one base

• Lateral area minus the area of one base

• Lateral area minus the area of two bases
