Question

the side of a cube are 10 cm each if its side are increased by 1 cm each calculate the percentage increase in its total surface area and volume​

Answer 1

Answer:

see the volume of cuboid initially=a^3=1000cm^3 on increasing the side,the side becomes 11cm ans cube if which is 1131cm^3 so Percentage increase is 11.31 percent in volume which in case of area 21 percent increase is seen

Answer 2

Step-by-step explanation:

volume of cube=10³

=1000cm³

Surface area=6•10²

=600cm²

new volume=11³

=1331cm³

new surface area=6•11²

= 726cm²

therefore increase in volume=1331-1000

=331cm³

therefore increase in surface area=726-600

=126cm²

Hope it helped you!!
