Question

5. Find the volume and total surface area of a
cube whose each edge is:
() 8 cm
(ii) 2 m 40 cm.​

Answer 1

Answer:

Edge of the given cube = 8 cm

Volume of the given cube = (Edge)3 = (8)3 = 8 x 8 x 8 = 512 cm3

Total surface area of a cube = 6(Edge)2 = 6 x (8)2 = 384 cm2

(ii) Edge of the given cube = 2 m 40 cm = 2.40 m

Volume of a cube = (Edge)3

Volume of the given cube = (2.40)3 = 2.40 x 2.40 x 2.40 = 13.824 m2

Total surface area of the given cube = 6 x 2.4 x 2.4 = 34.56 m2. Thats Your Answer I Hope It May Help You!!!!!!!!^^^^^^

Answer 2

Answer:

1/ Total surface area of a cube = 6a*a

=6*(8*8)

=6*64

=384cm square
