Question

a cuboidal vessel is 10 m long and 8 metre wide how high must it be made to hold 380 cubic metres of a liquid ​

Answer 1

Length   =10 m

breadth =8 cm

volume  =380 cm³

⇒l*b*h   =380

⇒10*8*h=380

⇒h        =38/8

   h         =4.75 m

Therefore,the vessel must be made to a height of 4.75 m to hold 380 cubic meters of a liquid.

Answer 2

Given:

• Length, l = 10 m

• Breadth, b = 8 m

• Volume of cuboid = 380 m³

To find out:

Find the height, h.

Formula used:

Volume of cuboid = length × Breadth × Height

Solution:

Volume of cuboid = length × Breadth × Height

→ 380 = 10 × 8 × h

→ 380 = 80h

→ h = 380/80

→ h = 4.75 m

Extra information:

• Perimeter of cuboid = 4 ( l + b + h )

• Perimeter of cube = 12 l

• Surface area of cuboid = 2 ( lb + bh + hl)

• Surface area of cube = 6 ( Edge ) ²
