STD 6 MATHEMATICS LESSON

TOPIC : MEASUREMENT

SUB TOPIC: VOLUME OF A CUBOID.

A C uboid is a figure with a square or rectangular base. Look at the picture of the cuboid below.

To calculate the volume of a cuboid, we say : Length × Width × height. The answer is in cubic units. Assuming the length is 20m Width is 5 m and Height is 10m.
∴ 20×5×10 = 1000m³.
D0 the following questions.
Calculate the Volume of the cuboid with the following measurements:
1. Length 20m , Width 3m, height 2m.

2. L=12, W=4, H= 3.

3. L=30, W=2, H=3

4. L=12, W= 3, H=5

5. L= 6, W=4,H=5

6. A Carton has a base of 5ocm by 20cm and a height of 40cm. What is its volume in cm³?

7. The base area of a square box is 16cm². What is its volume if the height is 3 cm?

8. The volume of a cuboid is 100. What is its height if the length 10 and Width is 2?
