Answer 1

$\bold{\underline{\underline{\huge{\sf{ANSWER\::}}}}}$

Given:

A cardboard box is 1.2m long, 72cm wide and 54cm high.

To find:

The bars of soap can be put into it if each bar measure 6cm × 4.5cm× 4cm.

Explanation:

We have,

• Length of the cardboard,l= 1.2m =120cm       [Convert into cm]
• Breadth of the cardboard,b= 72cm
• Height of the cardboard,h= 54cm

We know that volume of cuboid: Length×Breadth×Height   [cubic units]

Volume of the cardboard box= (120× 72× 54)cm³

Volume of the cardboard box= 466560cm³

Therefore,

Volume of each bar of soap= 6cm × 4.5cm× 4cm

Volume of each bar of soap= 108cm³.

Now,

Total number of bars of soap required for box:

→ $\frac{Total\:volume\:of\:cardboard\:box}{Volume\:of\:each\:bars's\:soap}$

→ $\cancel{\frac{466560}{108} }$

→ 4320 bars of soap.
