Surface Area and Volume Formulas
Below given is the table for calculating Surface area and Volume for the basic geometrical figures:
Name Perimeter Total Surface Area Curved Surface Area/Lateral Surface Area Volume Figure
Square 4a a2 —- —- Square
Rectangle 2(w+h) w.h —- —- Rectangle
Parallelogram 2(a+b) b.h —- —- Parallelogram
Trapezoid a+b+c+d 1/2(a+b).h —- —- Trapezoid
Circle 2 π r π r2 —- —- Circle
Ellipse 2π√(a2 + b2)/2 π a.b —- —- Ellipse
Triangle a+b+c 1/2 * b * h —- —- Triangle
Cuboid 4(l+b+h) 2(lb+bh+hl) 2h(l+b) l * b * h Cuboid
Cube 6a 6a2 4a2 a3 Cube
Cylinder —- 2 π r(r+h) 2πrh π r2 h Cylinder
Cone —- π r(r+l) π r l 1/3π r2 h Cone
Sphere —- 4 π r2 4π r2 4/3π r3 Sphere
Hemisphere —- 3 π r2 2 π r2
Answer:
Surface Area of a cuboid of length (l), breadth (b), and height (h) = 2 (lb + bh + lh)
Lateral Surface Area of cuboid = 2 (l + b)h.
Surface Area of a cube = 6 ✕ l2 where l is the length.
Lateral Surface Area of cube = 4 ✕ l^2, where l is the length.
Volume of cube=|^3
