Question

The formula to find the surface area of a cuboid of length (l), breadth (b) and height (h) is:

Answer 1

Step-by-step explanation:

Surface area of a cuboid of length = l

Surface area of a cuboid of breadth = b

Surface area of a cuboid of height = h

Surface area of a cuboid =  2 (l+b) h

                                          = 2lh + 2bh (Ans)

$\underline{\boxed{\bold{Important\;Information}}}$  

➠ There are 2 types of surface areas. Let us discuss both of them !

$\; \; \;$  

$\; \; \;$  

1. Total Surface Area

 $\; \; \;$  

• It the sum of areas of all the surfaces of a 3-dimensional shape.
• We have to include each and every surface in its calculation.

$\; \; \;$  

$\; \; \;$  

2. Lateral Surface Area

 $\; \; \;$  

• Usually , It the sum of areas of 4 surfaces of a 3-dimensional shape.
• We have to include 4 surface excluding roof and floor in its calculation.

$\underline{\boxed{\bold{Answer}}}$

Let's Start !

 $\; \; \;$  

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

 $\; \; \;$  

 $\; \; \;$  

Here are several important formulas !

$\; \; \;$  

1. Cuboid

$\; \; \;$  

$\bold { \red { :\implies TSA = 2(LH + HB + HL) } }$

$\bold{ \blue {:\implies CSA = 2H(L+B) } }$

$\bold{ \green {:\implies Volume = L \times B \times H } }$

 $\; \; \;$  

$\; \; \;$  

2. Cube

$\; \; \;$  

$\bold { \red { :\implies TSA = 6L^{2} } }$

$\bold{ \blue {:\implies CSA = 4L^{2} } }$

$\bold{ \green {:\implies Volume =L^3 } }$

$\; \; \;$  

$\; \; \;$  

3. Cylinder

$\; \; \;$  

$\bold { \red { :\implies TSA = 2\pi r(r+h) } }$

$\bold{ \blue {:\implies CSA = 2\pi rh } }$

$\bold{ \green {:\implies Volume =\pi r^2h } }$

 $\; \; \;$  

$\; \; \;$
