0.80 because when you line up the decimals 0.80 is bigger
0.80
0.08
When dividing two fractions, invert the second one and multiply the 2 top numbers and the 2 bottom numbers.
3/4 / 1/4 = 3/4 * 4/1 = 12/4 = 3
All sides of a square/cube are the same. Since this is a cube, you'll find the volume by "cubing" (get it?) 4.4m.
4.4³ or 4.4 * 4.4 * 4.4 = 85.184m³ but you can round that to 85m³
I hope that helps!
Imagine a corner of a cube.
It is made of three planes interesting at a single point
The image should help.
