Question

A cuboidal vessel is 10m long and 8m wide . How high must it be made to hold 380 cubic metres of a liquid ? ​

Answer 1

Answer:

length =10 m

length =10 mbreadth =8 cm

length =10 mbreadth =8 cmvolume =380 cm³

length =10 mbreadth =8 cmvolume =380 cm³⇒l×b×h =380

h =380⇒10×8×h=380

h=380⇒h =38/8

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

Answer:

$given \: = volume \: {380m}^{3} \\ \\ length \: = 10m \: \\ breadth = 8m$

$volum e \: = lbh$

$380 = 10 \times 8 \times h$

$h = \frac{380}{80}$

$h = 4.75$
