Question

Three identical cubes of side 4 cm are joined end to end. Find the total surface area and lateral surface area of the new resulting cuboid?

Answer 1

$\huge \bf \underline \purple{answer}$

Given:

$\huge \bf \boxed{ATQ}$

3 identical cubes of side 4cm are joined end to end.

_______________________________

now it's a cuboid since cube has all it's edges equal.

$\bf \underline{length \: of \: the \: cuboid}$

= 4 + 4 + 4 = 12cm

$\bf \underline{breadth \: of \: the \: cuboid}$

= 4cm

$\bf \underline{height \: of \: the \: cuboid}$

= 4cm

formula to find the total surface area of a cuboid is 2(lb + bh + lh)

= 2 [ (12 × 4) + (4 × 4) + (12 × 4) ]

= 2 ( 48 + 16 + 48 )

= 2 × 112

= 224cm²

______________________

hence, the total surface area of the cuboid is 224cm².
