Question

The volume of cuboid is240cm cubic.Find the its breath if its lengthis 8cm and heigth is 5cm​

Answer 1

Volume=lenght*breadth*height
Let the breadth be b
Given, l=8cm h=5cm and V=240cm^3
Therefore 240=8*5*b
240=40*b
B=240/40
B=6

Thank you

Answer 2

Answer :

➥ The breadth of a cuboid = 6 cm

Given :

➤ Volume of a cuboid = 240 cm³

➤ Length of a cuboid (l) = 8 cm

➤ Height of a cuboid (b) = 5 cm

To Find :

➤ Breadth of a cuboid (b) = ?

Solution :

Let ,

The breadth of cuboid be "l"

As we know that

$\tt{ : \implies Volume \: of \: cuboid = l \times b \times h}$

$\tt{ : \implies 240 = 8 \times 5 \times b}$

$\tt{ : \implies 240 = 40 \times b}$

$\tt{ : \implies 240 = 40b}$

$\tt{ : \implies \dfrac{24 \cancel{0}}{4 \cancel{0}} = b }$

$\tt{ : \implies \cancel{\dfrac{24}{4}} = b }$

$\bf{ : \implies \underline{ \: \: \underline{ \purple{ \: \: b = 6 \: cm \: \: }} \: \: }}$

Hence, the breadth of a cuboid is 6 cm.

⠀

Some releted formulae :

⪼ Total Surface area of cuboid = 2(lb + bh + lh)

⪼ Lateral surface area of cuboid = 2h(l + b)

⪼ Diagonal of cuboid = √( l² + b² +h²)

⪼ Perimeter of cuboid = 4(l + b + h)

Where,

• l is the length of cuboid
• b is the breadth of cuboid
• h is the height of cuboid
