Answer 2

$\huge\mathfrak\red{Answer :}$

$\huge\textbf{1) CSA of Cone :}$

[CSA = Curved Surface Area]

* Figures in attachment... (1)

Formula :-

$\dfrac{1}{2}$ × Perimeter of base × slant height.

= $\dfrac{1}{2}$ × 2πr × l

=> πrl

$\huge\textbf{2) CSA of Cuboid :}$

* Figure... (2)

S = 2lb + 2bh + 2hl

S = 2 (lb + bh + hl)

S = 2hl + 2hb

=> S = 2h(l + b)

$\huge\textbf{CSA of Cube :}$

* Figure..... (3)

TSA (total surface area) of cube = 6a²

In CSA of cube we have to reduce area of top and bottom of cube...

= 6a² - (a² + a²)

= 6a² - 2a²

=> 4a²
