Problem 1:Find the volume of a brick, knowing that

its length = 7 cm, its width= 5cm & its height=

lcm.

Answer:

The volume of the brick = length X width

X height

7 cm X 5 cm X 1 cm = 35 cm3

Problem 1:Find the volume of a brick, knowing that

its length = 7 cm, its width= 5cm & its height=

lcm.

Answer:

The volume of the brick = length X width

X height

7 cm X 5 cm X 1 cm = 35 cm3


Problem 2:A graduated cylinder contains 100 cm3

of water when an irregular object was put, the level of water became 150 cm3. Find the volume of the object

Answer:The volume of the object=The volume of water & the objective V2

–The volume of water V1150 cm3 – 100 cm3 = 50 cm3 .
