Question

what is the volume of a box whose each side is 30cm

Answer 1

Answer:

volume of box

Each side of box =30cm

Box is cube (All side are equal)

volume of cube = a³

a=30

a³=30³=27000

The volume of box is 27000cm

Answer 2

${\huge{\underline{\boxed{\red{\mathcal{Answer}}}}}}$

Given:

• Length of each Side of box = 30cm

To find:

• Volume of the box

Solution:

$\setlength{\unitlength}{4mm}\begin{picture}(10,6)\thicklines\put(0,1){\line(0,1){10}}\put(0,1){\line(1,0){10}}\put(10,1){\line(0,1){10}}\put(0,11){\line(1,0){10}}\put(0,11){\line(1,1){5}}\put(10,11){\line(1,1){5}}\put(10,1){\line(1,1){5}}\put(0,1){\line(1,1){5}}\put(5,6){\line(1,0){10}}\put(5,6){\line(0,1){10}}\put(5,16){\line(1,0){10}}\put(15,6){\line(0,1){10}}\put(4.6,-0.5){\bf\large 30 cm}\put(13.5,3){\bf\large 30 cm}\put(-4,5.8){\bf\large 30 cm}\end{picture}$

As all sides of the box are of 30cm,it is a cube.

=> Volume of cube = $side^3$

=> Volume of cubical box = $30^3$

=> Volume of cubical box = $27000 cm^3$

Formula Used:

• Volume of cube = $side^3$
