Question

perimeter of one face of cube in 40 m then its C.S.A is​

Answer 1

Answer:

all faces of cube are square in shape

hence perimeter of square =40 m

4×side =40 m

side = (40/4) m

side= 10 m

lateral surface area of cube = 4(side)^2

=4×(10)^2

=4×100

=400 metre square

Answer 2

Answer:

all the faces of cube are square in shape.

perimeter of square = 40m Side = 10m. C.S.A = 4(S)^2 = 4(10)^2 = 4× 100 = 400m^2 I hope it helps you g
