Question

the age of a cube is 6 cm find its total and lateral surface area​

Answer 1

Answer:

Lateral surface area =144cm²

Total surface are =216cm²

Step-by-step explanation:

There is a mistake in the question .question is like this "edge of cube is 6 cm find its total and lateral surface area"

Now , let edge of cube be x,and we know that cube has 4 walls , one base and one roof (upper face) all in all cube has total6 six faces of equal area because all edges of cube are same

Area of one face of cube =edge²=x²

Lateral area of cube = area of four walls

=4 x²

Here edge( x)=6cm

Lateral area of cube

=4(6)²=4(36)=144cm²

Total surface area of cube =area of six

faces

=6x²=6(6)²=6(36)=216cm²

Additional information--->

-------------------------------------

1)Volume of cube=edge³

2)Volume of cuboid=l×b×h

3)Lateral surface area of

cuboid=2(l+b)×h

4)Totoal surface area of

cuboid=2(l×b+b×h+l×h)

Where l=length,b=breadth,h=height

Answer 2

Answer:

edge of the cube = 6cm

lsa of a cube = 4a²

                    = 4×6×6

                    =144 cm²

tsa of a cube = 6a²

                    = 6×6×6

                    =216 cm²

the Lsa of the cube is 144cm² and tsa is 216cm²
