Answer 2

Hello friend!!!

Here's your answer

The edge of the cube measures 2m40cm which is 240cm or 2.40m

Total surface area for a cube is 6l^2 where l is the side of the cube.

So total surface area
=6 × 240^2
=6 × 57600
=345600cm^2
=34.56m^2

Also the volume of a cube is l^3 where l is the side of the cube.

Here, volume
= 240^3
=13824000cm^3
=13.824m^3


HOPE THIS HELPS..... :-)
