Question

If the length of a cuboid is 36 cm , breadth is 30 cm and the height is 24 cm , then its total surface area is​

Answer 1

Given:

• Length of cuboid = 36cm
• Breadth of cuboid = 30cm
• Height of cuboid = 24cm

To finD:

• Total surface area of cuboid

Solution:

We have length (36cm), breadth(30cm) and height(24cm) of cuboid are given.

To find total surface area of cuboid,

We know that :

• Total surface area of cuboid = 2(LB + BH + LH)

Where,

• L = Length of cuboid
• B = Breadth of cuboid
• H = Height of cuboid

Now, we have also a formula to find Total surface area of cuboid.

Putting values in formula:

Total surface area of cuboid = 2(LB + BH + LH)

→ Total surface area of cuboid = 2[(36×30)+(30×24)+(36×24)]

→ Total surface area of cuboid = 2( 1080 + 720 + 864)

→ Total surface area of cuboid = 2× 2664

→ Total surface area of cuboid = 5328cm²

Therefore,

• $\large{\text{\pink{Total\: surface\:area\:of\: cuboid\:=\:5328cm²}}}$

Answer 2

Step-by-step explanation:

Given,

Length, L =36 cm

Breadth, B =30 cm

Height, H =24 cm

Total surface area of cubiod =(LB+BH+LH) or (L*B + B*H

+ L*H)

=(36*30 + 30*24 + 36*24)

=(1080 + 720 + 864)

= 2664 sq.cm
