Question

The volume of a
cube is 8a cubic
units. If three such
identical cubes are
stacked, what is the
total surface area of
the cuboid formed?​

Answer 1

Step-by-step explanation:

Total surface area of a cube of side a=6a²

So, total surface area of 8 cubes =8×6A²=48².

When eight such cubes are stacked, the resulting figure will be a cube of

length =2a

breadth =2a

height =2a

And total surface area of the cube of side 2a=6(2a)² =24A²
