Answer 2

Given:-

• Side of cubic blocks
• Dimensions of cubic block

To find:-

• How many cubic blocks of wood can be cut.

Solution:-

Side of cubic blocks= 20 cm

Volume of cubic blocks= (A)³

(20)³

8000

Length of wooden block:- 2m

1m= 100 cm

1m= 100 cm2m= 200 cm

Breadth of wooden block= 80 cm

Height of wooden block= 40 cm

Volume of wooden block= L×B×H

200×80×40

640000 cm³

Number of boxes:- 640000÷8000

80 block.

So 80 cubic blocks can be made of wood.
