Question

8. The dimensions of a rectangular log of wood are 10m, 1.5m and 80cm. how many cubical blocks can be cut from it if the edge of a block is 50cm ?​

Answer 1

Answer:

Volume of cuboid=(1000 x 150 x 75)cm=11,250,000 cm 3

volume of cube=(50)3 cm 3=125000 cm 3

number of blocks

=volume of cuboid /volume of cube

= 11,250,000/125000

=90

➤ ➣ ➢ Solution ➤ ➣ ➢

• It can be determined from there volime
• Volume of cuboid = length *breadth *height= 2.5*15 *2m³=7.5m³
• Volume of cube = length ³=0.5³ m³=0.125m³
• Number of cubical blocks that can be cut =7.5/0.125=60
