Question

Two cube of edge 14cm are joined end to end to form a cuboid then the total surface area of cuboid is

Answer 1

Answer:

Total surface area of cuboid is 1960 cubic cm.

Step-by-step explanation:

Given : Two cubes of edge 14 cm each are joined end to end to form a cuboid

To find : The total surface area of the cuboid ?

Solution :

Two cubes of edge 14 cm each are joined end to end to form a cuboid

So, Length of cuboid = 14 cm +14 cm = 28 cm

Breadth of cuboid = 14 cm

Height of cuboid = 14 cm

Total surface area of cuboid is

$tsa = (lb + bh + lh) \\ = 2(28 \times 14 + 14 \times 14 + 14 \times 28) \\ = 1960 {cm}^{3}$

Hence, Total surface area of cuboid is 1960 cubic cm
