Question

Two cubes each with side 2 cm are joined to form a cuboid as shown. The total surface area of the cuboid formed is *​

Answer 1

Step-by-step explanation:

Side of the cube = 2 cm

Length of cuboid (l) = 4 cm

Height of cuboid (h) = 2 cm

Breadth of cuboid (b) = 2 cm

Total Surface area of cuboid =

• = 2 (lb + bh + lh)
• = 2 (4×2 + 2×2 + 4×2)
• = 2 ( 8 + 4 + 8 )
• = 2 × 20
• = 40 cm²

Answer 2

Answer:

16 cm(cube)

Step-by-step explanation:

lenght = 2+2 = 4

breadth= 2

height=2

volume of cuboid = (LxBxH)

= 4x2x2

= 16 cm(cube)
