Answer:
Formula to find volume of :
Cube = (side)3
Cuboid = l×b×h
Cylinder =pie×r2×h
Cone = 1/3pie×r2×h
Sphere = 4/3pie × r3
Hemisphere = 2/3pie × r3
Formula to find curved surface area of :
Cube = 4×(side)2
Cuboid = 2×(l×b)×h
Cylinder = 2×pie×r×h
Cone = pie×r×l
Sphere = 4×pie×r2
Hemisphere = 2×pie×r2
Formula to find total surface area of :
Cube = 6×(side)2
Cuboid = 2×(lb+bh+hl)
Cylinder = 2×pie×r(h+r)
Cone = pie×r(l+r)
Sphere =4×pie×r2
Hemisphere = 3×pie×r2
Hope it helps.
