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

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

এল-মৃত্যু পত্র x W x H = 486cm3

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

Length = Height x 2, which simplifies to এল-মৃত্যু পত্র = 2H
Width = Height / 2, which simplifies to W = 0.5H

আপনি then put them into the formula.

2H x 0.5H x H = 486 cm3

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