Question

7. A rectangular box is 2 m long and 3 m wide. How many cubic metres of sand are needed to fill the box upte
a depth of 12 cm​

Answer 1

Step-by-step explanation:

Hi there,

Length = 2m

Width = 3.5m

Depth = 12cm = 0.12m

Volume = length x width x depth

Volume = 2 x 3.5 x 0.12

Volume = 0.84m^3 of sand required

Answer 2

Answer:

0.72 m³ of sand is needed.

Explanation

Given

• The length of the rectangular box = 2m
• The width of the rectangular box = 3m

To Find

• How many m³ of sand is needed to fill the box upto a depth of 12 cm or 0.12 m

Solution

[ A rectangular box refers to a cuboid.

A rectangular box refers to a cuboid.The number of meter cubes of sand that can be filled in the rectangular box is same as the volume of the rectangular box in m³ with dimensions 2m, 3m and 0.12m. ]

Volume of a cuboid = Length × breath × height

Volume = 2m × 3m × 0.12 m

Volume = 6m² × 0.12m

Volume = 0.72 m³

0.72 m³ sand is needed.
