Question

What is the uses of surface area and volume and write the formula cube and cuboid?

Answer 1

Answer:

It requires in many cases..

Such as for finding the reqd surface of the things and the volume for reqd amount of spaces.....

Formula of cube:

Curved surface area=πrl

Total surface area= πr(l+r)

Volume=1/3πr^2h

Formula of cuboid:

T.S.A=2(lb+bh+hl)

Lateral surface area=2(l+b)h

Volume=l×b×h

$\Large\mathcal\purple{CUBOID}$

$\implies \: lsa = 2(l + b)h \\ \\ \: \implies \: tsa = 2(lb + bl + hl) \\ \\ \implies \: volume \: = l \times b \times h$

$\Large\mathcal\blue{CUBE}$

$\implies \: lsa = {4a}^{2} \\ \\ \implies \: tsa = {6a}^{2} \\ \\ \implies \: volume = {a}^{3}$
