Question

5 identical cubes with length measuring 8.5 cm are joined. what will be the surface area of the new 3D shape formed

Answer 1

Since 5 Identical cubes of length 8.5cm are joined hence length will add up of all

8.5 * 5 = 42.5 cm

The breath and height will reamin the same

Now total surface area of the new cuboid will be
2(lb+bh+hl)
$2(42.5 \times 8.5 + 8.5 \times 8.5 + 42.5 \times 8.5) \\ = 1589.5 \: {cm}^{2}$


That is your answer
