Answer 1

Bonjour!!!!!

Here's your answer....

Hope it helps...!!

Answer 2

$\underline\mathfrak\pink{Given:-}$

• The volume of cuboid is 1800cm³
• it's length is 15cm and height is 12cm.

$\large\underline\mathfrak{To \: find:-}$

• Find the breadth of the cuboid ....?

$\large\underline\mathfrak\pink{Solutions:-}$

• Let the breadth of the cuboid be x cm.

• Let the length = 15cm
• height = 12cm

Volume of a cuboid = l × b × h

$\: \: \: \: \: \leadsto \: \: {1800} \: \: = \: \: {15} \: \times \: {x} \: \times \: {12}$

$\: \: \: \: \: \leadsto \: \: {1800} \: \: = \: \: {180x}$

$\: \: \: \: \: \leadsto \: \: {x} \: \: = \: \: \cancel{\frac{1800}{180}}$

$\: \: \: \: \: \leadsto \: \: {x} \: \: = \: \: {10}$

Hence, the breadth of the cuboid is 10cm.

$\underline\mathfrak\pink{More \: \: Important:-}$

1. Volume of cuboid = l × b × h
2. Surface area of cuboid = 2(lb + bh + hl)
3. Surface area of 4 wall = 2(l + b) × h
4. Diagonal of cuboid = √l² + b² + h²
5. Height of cuboid = volume/base area
6. Area of cuboid = volume/height

where,

• a = area
• d = diagonal
• l = length
• b = breadth
• h = height
