Question

A tank measures 2 m in length, 1.6 m in width and 1 m in depth. Water is there upto 0.4 m height.
Bricks measuring 25 cm x 14 cm x 10 cm are put into tank so that the water may come up to the
top.
Each brick absorbs water equal to
th of its own volume. How many bricks will be needed?​

Answer 1

$\Large{\red{\underline{\underline{\tt{AnSweR:}}}}}$

length of water tank =4m

Breadth =2m

height =50cm=10050 m

Volume of tank =l×b×h

=4×2×10050

=4cu.m

∴ Volume of water tank =4cu.m

1cu.m=1000litre 

4cu.m=(4×1000)

=4000 litre water can be stored in tank.

Answer 2

Answer:

length of water tank =4m

Breadth =2m

height =50cm=10050 m

Volume of tank =l×b×h

=4×2×10050

=4cu.m

∴ Volume of water tank =4cu.m

1cu.m=1000litre

4cu.m=(4×1000)

=4000 litre water can be stored in tank.
