Question

four cubes each of side 8 cm,are placed adjacent to each other find the total surface area of the cuboid formed​

Answer 1

Answer:

1152cm²

Step-by-step explanation:

4 cubes of side 8 cm placed adjacent to each other form a cuboid of

length = 8cm + 8cm + 8cm + 8cm = 32 cm

breadth = still same = 8 cm

height still same = 8 cm

Total surface area = 2(lb + bh + hl)

          = 2(32*8 + 8*8 + 8*32) cm²

          = 2(256 + 64 + 256) cm²

          = 2(576) cm²

          = 1152 cm²

Surface area of the cuboid formed is 1152 cm²

Answer 2

Question:-

• four cubes each of side 8 cm,are placed adjacent to each other find the total surface area of the cuboid formed.

To Find:-

• Find the total surface area of the cuboid.

Given:-

• Four cubes each of side 8 cm,are placed adjacent to each other.

Solution:-

Here ,

• Length is 32 cm

• Breadth is 8 cm

• Height is 8 cm

$\tt\implies \: Total \: surface \: area = 2( lb + bh + hl )$

$\tt\implies \: Area = 2( 32 \times 8 + 8 \times 8 + 8 \times 32 )$

$\tt\implies \: Area = 2( 256 + 64 + 256 )$

$\tt\implies \: Area = 2( 576 )$

$\tt\implies \: Area = 1152 { cm }^{ 2 }$

Hence ,

• Total surface area of the cuboid is 1152.
