Question

A rectangular sand box is $5m$ wide and $2m$ long. How muany cubic metres of sand are needed to fill the box upto a depth of $10cm$?

• A. $1$
• B. $10$
• C. $100$
• D. $1000$

Answer 1

The correct option is A $1$

The box has a shape of a cuboid.

Volume of a cuboid of length $l$, breadth $b$ and height $h$ $=l\times b\times h$ depth $=$ height $=10cm=0.1m$

So, the volume of the sand that can be filled in the box $=5\times 2\times 0.1=1m^3$
