Cuboid:
TSA = 2(lb+bh+lh)
LSA = 2h(l+b)
Volume = lbh

Cube:
TSA = 6l²
LSA = 4l²
Volume = l³

Cylinder:
TSA = 2πr(r+h)
CSA = 2πrh
Volume = πr²h

Square:
Perimeter = 4l
area = l²

Rectangle:
Perimeter = 2(l+b)
area = lb

Circle:
Perimeter = 2πr
area = πr²

Triangle:
Perimeter = a+b+c
area = √s(s-a)(s-b)(s-c)
where s = (a+b+c)/2
perimeter is for 2D objects
oops... i didnt see properly..
:)
sry...in over look i missed perimeter of circle
thank u tps a lottt.....:)

Cuboid TSA=2(lb+bh+lh) CSA=2(l+b)h. Or if you are given with perimeter you can multiply it with height. Volume=lbh Cube TSA=6a^2 CSA=4a^2 Volume=a^3. Or a*a*a Cylinder TSA=2πr(h+r) CSA=2πrh Volume=πr^2h Square Perimeter =4s Area=s^2 Rectangle Perimeter=2(l+b) Area=lb Circle Perimeter=2πr Area=πr^2 Triange Perimeter= sum of all sides Area=1/2 b*h
