Question

two cubes of side 4 cm are joined to each other side by side. find the surface area of resulting cuboid​

Answer 1

Answer:

160cm^2

Step-by-step explanation:

After joining the cubes a cuboid will be formed of dimensions

4×8×4

Hence, Surface Area of Cuboid is =2(4×8)+2(8×4)+2(4×4)=160 cm^2

Answer 2

Given:-

• Two cubes of side 4cm are joined to each other side by side.

To Find:-

• Find the surface area of resulting cuboid.

Concept:-

• Firstly,let's understand the concept. Concept used here is Total Surface of a Cuboid.Substitute the given values in the equation and solve it to find the surface area of the resulting cuboid.

Formulae Applied:-

• Total Surface Area of a cuboid = 2(lb + bh + hl)

Solution:-

Length = 4 + 4 = 8cm

Breadth = 4cm

Height = 4cm

TSA = ??

TSA of a Cuboid = 2(lb + bh + hl)

According to the Question we have!

⟹ 2(lb + bh + hl)

⟹ 2[(8 × 4) + (4 × 4) + (8 × 4)

⟹ 2[32 + 16 + 32]

⟹ 2[80]

⟹ 2 × 80

⟹ 160

⟹ 160cm^2.

Therefore,

⟹ The Surface area of the resulting cuboid is 160cm^2.
