Question

Three cubes each of side 1 cm are joined end to end the surface area of the resulting solid is

Answer 1

Answer: The surface area of the resulting solid is 14 cm^2.

Step-by-step explanation:

When three cubes each of side 1 cm are joined end to end, the resulting solid is cuboid.

The length of the resulting solid, l= 1 + 1 + 1= 3 cm

The breadth of the resulting solid, b= same as the side of given cube= 1 cm

The height of the resulting solid, h= same as the side of given cube= 1 cm

So,

The surface area of the resulting solid= 2(lb + lh + bh)

Plugging the value of l, b, and h, we get

=> 2(3*1 + 3*1 + 1*1)= 2(3 + 3 +1)= 2*7

=> 14 cm^2

Answer 2
