Question :

A rectangular cuboid of length 30 cm , breadth 25 cm and height 12 cm, then find it's volume and surface area.

 \\ \\

AsWer:

Volume of rectangular cuboid be 900 cm³

Surface area be 1320 cm².

 \\ \\

Explanation :

 \:  \:  \:  \:  \:  \tt{We \:  know \:  the  \: formula \:  for }</p><p> \\  \:  \:  \:  \:  \:  \tt{Volume \:  of  \: cuboid.}

 \tt \: ie \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \tt{l \times b \times h}

 \\

Putting the given value,

  \:  \:  \:  \:  \:  \:  \tt \leadsto30 \times 25 \times 12.

 \:  \:  \:  \:  \:  \:   \tt\leadsto900 \:  {cm}^{3} .

 \\ \\

Now,

It's Surface area be

 \:  \:  \:  \:  \:  \:  \tt2(l + b) \times h

 \\

Putting given value,

 \:  \:  \:  \:  \:  \:  \tt \leadsto2(30 + 25) \times 12

 \:  \:  \:  \:  \:  \:  \leadsto1320 \:  {cm}^{2} .

Therefore, the value Volume be 900 cm³ and it's Surface area be 1320 cm².
