Question

A rectangular tank is 3.5 m long and 0.5 m deep . Find the width of the tank if it is volume is 4.2 cu.m.​

Answer 1

Answer:

Step-by-step explanation:

V=3x2x1=6m^3

We know that 1L = 0.001m^3. Therefore we can use dimensional analysis.

6m^3 x (1L/0.001m^3)

= 6000 Litres

Answer 2

Volume of a rectangular tank = length x depth x width

Length = 3.5 m

Depth = 0.5 m

Volume = 4.2 cu. m.

Therefore,

4.3 = 3.5 x 0.5 x Width

Width = 4.3/(3.5 x 0.5)

= 4.3/1.75

= 2.457142857....

Width of the tank is 2.457142857.... metres.
