Answer 2

$\sf{For \: Cube}$

• Surface Area of Cube :

$:\implies \sf{T S A = 6a^{2}}$

• Curved Surface Area :

$:\implies \sf{C S A = 4a^{2}}$

• Volume :

$:\implies \sf{V = a^{3}}$

Where,

" a " → Side of the cube

$\sf{For \: Cylinder}$

• Surface Area of Cylinder :

$:\implies \sf{T S A = 2 \pi r (r + h) }$

• Curved Surface Area :

$:\implies \sf{C S A = 2 \pi rh }$

• Volume :

$:\implies \sf{V = \pi r^{2}h }$

Where,

" π " → Pie (22/7)

" r " → Radius of the cylinder

" h " → Height of the cylinder

$\sf{For \: Cuboid}$

• Surface Area of Cuboid :

$:\implies \sf{T S A = 2(lb + bh + hl) }$

• Curved Surface Area :

$:\implies \sf{C S A = 2(l + b)h }$

• Volume :

$:\implies \sf{V = l \times b \times h }$

Where,

" l " → Length of the Cuboid.

" b " → Breadth of the Cuboid.

" h " → Height of the Cuboid.
