The internal length, breadth and height of a rectangular box A are 20

1.	The internal length, breadth and height of a rectangular box A are 20 cm,18 cm and 15 cm respectively and that of box B are 18 cm,12 cm and 5 cm respectively. The volume of box A is how many times that of box B ?1. 42. 53. 64. 3
Answer» Correct Answer - Option 2 : 5 Given: Length of box A = 20 cm Breadth of box A = 18 cm Height of box A = 15 cm Length of box B = 18 cm Breadth of box B = 12 cm Height of box B = 5 cm Formula used: Volume of cuboid = Length × Breadth × Height Calculations: Volume of box A = 20 × 18 × 15 ⇒ 5400 cm³ Volume of box B = 18 × 12 × 5 ⇒ 1080 cm3 (Volume of box A) ÷ (Volume of box B) = 5400 ÷ 1080 ⇒ (Volume of box A) ÷ (Volume of box B) = 5 ⇒ Volume of box A = 5 × Volume of box B ∴ The volume of the box A is 5 times of the volume of box B

The internal length, breadth and height of a rectangular box A are 20 cm,18 cm and 15 cm respectively and that of box B are 18 cm,12 cm and 5 cm respectively. The volume of box A is how many times that of box B ?1. 42. 53. 64. 3

Answer» Correct Answer - Option 2 : 5

Given:

Length of box A = 20 cm

Breadth of box A = 18 cm

Height of box A = 15 cm

Length of box B = 18 cm

Breadth of box B = 12 cm

Height of box B = 5 cm

Formula used:

Volume of cuboid = Length × Breadth × Height

Calculations:

Volume of box A = 20 × 18 × 15

⇒ 5400 cm³

Volume of box B = 18 × 12 × 5

⇒ 1080 cm3

(Volume of box A) ÷ (Volume of box B) = 5400 ÷ 1080

⇒ (Volume of box A) ÷ (Volume of box B) = 5

⇒ Volume of box A = 5 × Volume of box B

∴ The volume of the box A is 5 times of the volume of box B
