A solid metal block is 25 cm long ,15 cm wide and 10 cm high.it is cut into solid cubical blocks of the same size.find the number of cubical bloks,if each side measures 5 cm
Answers
Answer:
The total number of cubical blocks will be 30.
Step-by-step explanation:
Given the sides of block ,
L = 25 cm
W = 15 cm
H = 10 cm
Hence volume of wooden block = L x B x H
= 25 x 15 x 10
= 3750 cm³
Side of the small cube = 5 cm
=> Volume of the small cube = 5³ = 125 cm³
Since the larger block is cut into several number of cubical pieces, Hence
n x volume of cubical piece = volume of metal block
where n = number of cubical blocks
=> n x 125 = 3750
=> n = 3750/125 = 30
Hence the number of cubical blocks will be 30.
