Answer 2

Given:-

•Volume of a cuboid = 36000cm^3 and we are given breadth is 30cm and height is 20cm.

To Find:-

•Find the length.

Solution:-

we have,

• Volume of cuboid = 36000 cm^3
• Breadth = 30cm
• Height = 20cm

Using Formula:

$\: \: \sf \: volume \: of \: cuboid = length \times breadth \times height$

Now put the values here

$\: \: \sf \: 36000 = l \times 30 \times 20 \\ \\ \: \: \sf \: 36000 = l\times 600 \\ \\ \: \: \sf \: length = \frac{36000}{600} \\ \\ \: \: \sf \: length \: = 60cm$

Hence,Length of Cuboid is 60cm.

• L denotes Length
• B denotes Breadth
• H denotes Height

$\: \: \sf \: volume \: of \: cube = {(side)}^{3} \\ \\ \: \: \sf \: length \: of \: cuboid = \frac{volume \: of \: cuboid}{breadth \times height} \\ \\ \: \: \sf \: breadth \: of \: cuboid = \frac{volume \: of \: cuboid}{length \times height} \\ \\ \: \: \sf \: height \: of \: cuboid = \frac{volume \: of \: cuboid}{length \times breadth}$
