The total surface area of a cube is 1350 m2, find its volume.
The volume of a cuboid is 1200 cm°. Its length is 15 cm, breadth 10 cm Find out its
height?
What would the total surface area of a cubical box be if :-
(i) each side is doubled?
(i) each side is tripled?
(iii) each side is made n times?​

Answer 1

Step-by-step explanation:

Total surface area of cube=6l square

1350=6*l2

1350÷6=l2

225=l2

l=15

Volume of cube=l3

=15*15*15

=3375m2

Volume of cuboid=l*b*h

1200=15*10*h

1200=150*h

1200÷150=h

h=8.
