4. Find the volume of a water tank which is 250cm long, 160cm wide
and 80cm deep.
A 20 litres
B. 32 litres
C. 40 litres
D. 320 litres
E 3200 litres​

E

Step-by-step explanation:

=160*250*80

=3200000cm^3

also 1000cm =1 litres

therefore 3200000cm3 =3200litres

that's all have fun

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.

solving with completing the square
