Question

Find the volume and surface area of a cuboid 16m long, 14 m broad and 7 m high.


​

Answer 1

Step-by-step explanation:

$\large\underline{\bf{Solution \: \: 1}}$

Question:-

• Find the volume and surface area of a cuboid 16m long, 14 m broad and 7 m high.

To find:-

• Volume and surface area.

Figure:-

• Cuboid

Formula used:-

$\small\boxed{\sf{Volume \: of \: cuboid = l \times b\times h}}$

$\small\boxed{\sf{Surface \: area = 2(lb + bh + lh)}}$

Solution for Volume:-

$\large\underline{\sf{Volume _{cuboid} = l \times b\times h}}$

Substituting the values we get:-

$\large\underline{\sf{ 16m \times 14m \times 7m}}$

$\large\underline{\sf{ \implies1568 {m}^{3} }}$

$\large\underline{\bf{Solution \: \: \: 2}}$

Solution for surface area:-

$\large \underline {\sf{Surface \: area_{cuboid} = 2(lb + bh + lh)}}$

Substituting the values we get:-

$\large\underline{\sf{2(16 \times 14 + 14 \times 7 + 16 \times 7) {m}^{2} }}$

$\large\underline{\sf{2 \times {434m}^{2} }}$

$\large\boxed{\sf{ \implies{868m}^{2} }}$

Answer 2

Answer:

Volume = (16 x 14 x 7) m3 

= 1568 m3.  Surface area

= [2 (16 x 14 + 14 x 7 + 16 x 7)] cm2 

= (2 x 434) cm2 

= 868 cm2
