Question

A child playing with building blocks, which are of the shape of cubes, has built a structure as shown in the figure. If the edge of each cube is $3$ cm, find the volume of the structure built by the child.

• A. $270c{m}^3$
• B. $243c{m}^3$
• C. $216c{m}^3$
• D. $189c{m}^3$

Answer 1

The correct option is A $270c{m}^3$

Number of cubes$=10$

Volume of each cube$={\left(3\right)}^3=27c{m}^3$

Volume of structure$=10\times 27=270c{m}^3$
