Question

Count the $E$ shape cubes with $0.01$ m side for each cube and also find the volume of a cube in cubic centimetre.

• A. $0.0003{cm}^3$
• B. $30.03{cm}^3$
• C. $0.00003{cm}^3$
• D. $0.003{cm}^3$

Answer 1

The correct option is D $0.003{cm}^3$

Number of cubes $=30$
Side of each cube $=0.01$ m
Volume of a cube $=$ side $\times$ side $\times$ side or $s^3$
So, volume of one cube $=$ $0.01\times 0.01\times 0.01=0.000001m^3$
Volume of $30$ cubes $=$ $30\times 0.000001=0.00003$ $m^3$
Volume of $30$ cubes in cubic centimetre $=$ $0.0003\times 100=0.003$ ${cm}^3$
