Question

find the volume of the box in cubic metre with length 120cm breadth 100cm and height 150cm​

Answer 1

Given :-

• Length of box = 120 cm
• Breadth of box = 100 cm
• Height of box = 150 cm

To find :-

• Volume of box

Solution :-

• 1m = 100cm

→ Length = 120/100 = 0.12m

→ Breadth = 100/100 = 1m

→ height = 150/100 = 0.15m

Now, volume of box

→ length × breadth × height

→ 0.12 × 1 × 0.15

→ 0.018m³

Hence,

• Volume of box is 0.018m³

Extra Information :-

• Total surface area of cuboid = 2(lb + bh + lh)
• Curved surface area of cuboid = 2(l + b)h
• Total surface area of cube = 6a²
• Curved surface area of cube = 4a²
• Volume of cube = a³

Answer 2

$\star\:\:\:\bf\large\underline\purple{Given:—}$

☞︎︎︎ Length of the box = 120 cm

☞︎︎︎ Breadth of the box = 100 cm

☞︎︎︎ Height of box = 150 cm

$\star\:\:\:\bf\large\underline\purple{To\:find:—}$

Volume of the box in cubic metre

$\star\:\:\:\bf\large\underline\purple{Solution:—}$

Length of the box = 120 cm = 1.2 m

Breadth of the box = 100 cm = 1 m

Height of the box = 150 cm = 1.5 m

As we know that,

$\boxed{\bf{\blue{★Volume=length×breadth×height}}}$

= 1.2 × 1 × 1.5 m³

= 1.8 m³

Hence,volume of the box is 1.8 m³
