Question

If a box is $\frac{1}{4}$ filled contains $5$ small cubes each of volume $1$ cubic units, then find out the volume of the box.

• A. $25$ cu.
• B. $20$ cu.
• C. $15$ cu.
• D. $5$ cu.

Answer 1

The correct option is B $20$ cu.

Since the box is $\frac{1}{4}$ filled with the given cubes , we need to multiply the total volume of the given cubes by $4$ to get the total volume of the box.

Given, Volume of one cube is $1cu.$

$\therefore$ Volume of $5$ cubes will be $5\times 1cu.=5cu.$

$\therefore$ Volume of the box will be $4\times 5cu.=20cu.$

Therefore, option $B$ iss correct.
