Question

Perimeter of one face of cube is36cm.Find its total surface area

Answer 1

Answer:

Step-by-step explanation:

PERIMETER OF ONE FACE= 4*A,

WHERE A= SIDE OF THE CUBE.

SO A= 36/4=9 CM.

SURFACE AREA=6*A^2( BECAUSE CUBE HAS 6 EQUAL SQUARE FACES

)= 6*(9)^2=6*81=486.

Answer 2

Perimeter of one face of cube=36cm

so, 36cm = 4*Edge

Edge=36/4=9cm

Surface area of one face=9^2=81cm^2

A cube has 6 face.

so, total surface area =6×81=486cm^2
