Answer 1

Step-by-step explanation:

${8}^{3 } = 512 {cm}^{3}$

13.824m³

Answer 2

Answer:

Step-by-step explanation:

1) We know about the formula of volume of cube =a^3

Here a=8 I. E 8×8×8=512

Total surface area=6^2

I.e 6×8×8=384

Coming to second problem

I. E here 8m 40cm just we have to convert meters into centimetres right, I'm doing the same thing, 1m =100 centimetres so 2m 40 =2×100+40=240cm

Then coming to volume and surface area of cube I. E

Volume=240×240×240=2,304,000

Total surface area =6×240×240=345,600
