Question

A cuboidal water tank is 10m long,8m wide . How gh it be made to hold 380 cubic meter of a liquid

Answer 1

l=10m
b=8m
Let the height be h 
Volume=l×b×h
10×8×h=380
          h=380/80
          h=4.75m

The height of the tank is 4.75 m

Answer 2

Answer:

• Length of cuboidal vessel = 10m
• Breadth of cuboidal vessel = 8m
• Height = ?

$\\ \large{ \underline{ \boxed{ \sf{volume = l \: \times \: b \: \times h \: }}}} \\ \\ \\ \implies \sf \: 10 \times 8 \times h = 380 \\ \\ \\ \implies \sf \: 80 \times h = 380 \\ \\ \\ \implies \sf \: h = \ \cancel\frac{380}{80} \\ \\ \\ \implies \sf \: h = 4.75$

Therefore, height of cuboidal vessel is 4.75 m.
