Question

area of all faces of cube is________​

Answer 1

Answer:

10a

2

The cubes of sides a are joined face to face , the resultant figure is cuboid which has the same breadth and height as the joined cubes has the length twice of the length of a cube i.e.

l=2a, b=a

Thus the total surface area of the cuboid = 2(lb+bh+hl)

=2(2a x a + a x a +a x 2a )

= 2(2a

2

+a

=2x5a

$hello$

Answer : 6a2

‎

Explanation:

The surface area of a cube = 6a2

Where a is the length of the side of each edge of the cube.

Put another way, since all sides of a cube are equal, a is just the lenght of one side of a cube. We have 96 = 6a2 → a2 = 16, so that's the area of one face of the cube.
