4Answer:
If a cuboidal metal block of dimensions 20cm * 20cm * 12 cm weighs 6 kg .
Then the weight of a block of the same metal of size 10cm * 8cm * 8cm is 1.25 kg.
Step-by-step explanation:
Given:
The dimension of the first cuboidal metal block = 20 × 20 × 12
The dimension of the first cuboidal metal block = 10 × 8 × 8
Find: the weight of a second block
Volume of first cuboid metal block = lbh = 20 × 20 × 12 =4800 cubic cm
Weight of this = 6 kg
Volume of second cuboid metal block = lbh = 10 × 8 × 8 =640 cubic cm
Find the weight of the second cuboid metal block
Used unitary method
1440 cubic cm 6kg
640 cubic cm ?
The weight of second cuboid metal block = 4800÷ (6 × 640)= 4800 ÷ 3840 = 1.25 kg.
