Question

find the total surface area lateral surface area and length of diagonal of a cube whose edge is 4.5​

Answer 1

total surface area = 6a^2 ( a = 4.5)

6×45/10 = 3×9 =27 cm^2.

lateral surface area = 4a^2 = 4 ×45/10 = 180/10

= 18 cm^2.

diagonal of a cube = under root 3a

= under root 3× 45/10 = 3 under root 3/2 cm

Answer 2

Answer:

LSA of cube 4a square so; ans is 128
