Question

A solid metal block is 25cm long, 15cm wide and 10cm high. It is cut into solid cubical

blocks of the same size. Find the number of cubical blocks, if each side measures 5cm. ​

Answer 1

Answer:

The total number of cubical blocks will be 30. Hence the number of cubical blocks will be 30.

Answer 2

Given:

• Dimensions of the solid metal block = 25cm, 15cm and 10cm
• Measure of side of the cubical block = 5cm

To find:

• Number of cubical blocks.

Solution:

• No. of blocks = vol. of metal block/vol. of cubical block

★ Volume of metal block,

→ Length × Breadth × Height

→ 25 × 15 × 10

→ 3750cm³

★ Volume of cubical block,

→ (Side)³

→ (5)³

→ 125cm³

★ Now, number of blocks,

→ 3750/125

→ 30 blocks

Hence, the number of cubical blocks is 30.
