# Lateral Surface Area of Rectangular Right Wedge Calculator

Rectangular right wedge refers to the right triangular prism turned, in a way that it rests on one of its lateral rectangular faces. Right wedge is a parallel side triangle with three trapezoid faces. It is a parallelepiped where the face is collapsed into line. Lateral surface area is the area of all the sides excluding the top and base. Use our online calculator to find the lateral surface area of rectangular right wedge by entering the sides of bases and height.

#### Formula:

LSA = (1/2) x (a + c) x √((4 x h) + (b x b)) + (b x √((h x h)+((a-c)2))) Where, h = Height a = Length of Base A b = Length of Base B c = Length of Base C LSA = Lateral surface area of Rectangular Right Wedge

### Example:

A right rectangular wedge with height 7cm, lengths 5, 8 and 10 cm an LSA?

#### Solution:

LSA = (1/2) x (a + c) x √((4 x h) + (b x b)) + (b x √((h x h)+((a-c)2)))
= (1/2) x (5 + 10) x √((4 x 7) + (8 x 8)) + (8 x √((7 x 7)+((5 - 10)2)))
= 130.1171 cm2
