Sure, I'll help! I'll take bạn through the first half of the sum, and leave the rest to you.

So, bạn know that the surface area is 486cm3. The formula to find out the surface area is length x width x height. So thats:

l x W x H = 486cm3

Now, this becomes algebraic. bạn need to find a common length that the others are all relative to, which is given: height.

Length = Height x 2, which simplifies to l = 2H
Width = Height / 2, which simplifies to W = 0.5H

bạn then put them into the formula.

2H x 0.5H x H = 486 cm3

See how bạn go from here. If bạn need anymore help, just ask.
