Question

The dimensions of a brick is $25cm\times 10cm\times 8cm$. The volume of $15$ such bricks is ___.

• A. $10000c{m}^3$
• B. $20000c{m}^3$
• C. $60000c{m}^3$
• D. $30000c{m}^3$

Answer 1

The correct option is D $30000c{m}^3$

The brick is a cuboid.
Volume of the brick, $V=l\times b\times h$, where $l$ = length, $b$ = breadth, and $h$ = height of the brick.
Hence, volume of one brick = $25cm\times 10cm\times 8cm=2000c{m}^3$
$\Rightarrow$ Volume of $15$ bricks, $V=15\times 2000c{m}^3=30000c{m}^3$
