Question

Find the volume of a cuboid whose dimensions are:
(a) length = 15 cm, width = 12 cm and height = 8 cm​

Answer 1

Given

• Length of the cuboid = 15cm
• Width of the cuboid = 12cm
• Height of the cuboid = 8cm

⠀

To find

• Volume of the cuboid.

⠀

Solution

• As we have dimensions of the cuboid. Using the formula of Volume of Cuboid.

⠀

☆ Volume = l × b × h

⠀

• Putting the values

⠀

→ Volume = 15 × 12 × 8

→ Volume = 15 × 96

→ Volume = 1,440cm³

⠀

Hence,

• Volume of the cuboid is 1,440cm³.

⠀

⠀⠀⠀Formulae related to volumes

⠀

→ Volume of cube = a³

⠀

→ Volume of cone = ⅓ πr²h

⠀

→ Volume of cylinder = πr²h

⠀

→ Volume of sphere = 4/3 πr³

⠀

→ Volume of hemisphere = 2/3 πr³

• We know that ,

$\sf\red{Volume \ of \ cuboid = lbh}$

$\tt{= \ 15 \ x \ 12 \ x \ 8 }$

$\tt{ = \ 1440 \ cm^3}$

• LSA of cuboid = 2 ( l + b )h

• TSA of cuboid = 2 ( lb + bh + lh )

• Where l = Length , B = Breath and h = height.
