Question

Edge of a cube measure $25m$ and $l=20m,b=2m,h=3m$ are the measures of a cuboid. Which of the above has larger volume?

• A. Cuboid
• B. Cube
• C. Both are equal
• D. None of these

Answer 1

The correct option is B Cube

For cube $:$

$\Rightarrow$ Edge of cube $\left(l\right)=25m$

$\Rightarrow$ Volume of cube $=(l{)}^3$

$=(25{)}^3$

$=15625m^3$ --- ( 1 )

For cuboid $:$

$\Rightarrow$ $l=20m,b=2m,h=3m$

$\Rightarrow$ Volume of a cuboid $=l\times b\times h$

$=20\times 2\times 3$

$=120m^3$ --- ( 2 )

From ( 1 ) and ( 2 ),

Volume of cube $>$ Volume of cuboid.

$\therefore$ We can see cube has larger volume.
