Question

Sam has bricks of height 10 cm, he wants to stack them one above the other to achieve a height of 2 meter. How many bricks will he require?

• A. 0.2
• B. 200
• C. 20
• D. 2

Answer 1

The correct option is C 20

We know that, 1 m = 100 cm.
Sam wants to stack the bricks up to the height of 2 meter.
Thus, $2m=100\times 2=200cm$
The height of 1 brick is given as 10 cm.
So, $\frac{200cm}{10cm}=20$ bricks are required to arrange the bricks in stack up to 2 meter.
