a=8*1*1=8cb m
b=8*2*0.5=8cb m
c=4*2*1=8cb m
d=4*1*0.2=0.8cb m which is wrong
D is the wrong answer.

8 x 1 x 1 = 8, so that's ok.
8 x 2 x 0.5 = 8, so that's ok.
4 x 2 x 1 = 8, so that's ok.
4 x 1 x 0.2 = 0.8 so that's wrong.
d.

The answer is d.
Multiply the three numbers together for each possibility.
d) 4 x 1 x 0.2 = 0.8 m³ â 8 m³
The other three are fine.

a = 8 cubic metres
b = 8 cubic metres
c = 8 cubic metres
d = .8 cubic metres (decimal 8 cubic metres)
so d is the correct answer

Just multiply the numbers... if the answer is not 8 then it is the answer to the question... which in this case letter d...
4*1*0.2= 0.8
