` = "Trapezoid Volume Surface Area"`

Enter a value for all fields

The **Trapezoid Volume Surface **calculator computes the surface area of a trapezoid volume shape based on the dimensions. The surface area includes the four sides and the top.

**INSTRUCTIONS**: Choose units and enter the following:

- (
**a**) Width of Top - (
**b**) Length of Top - (
**A**) Width of Bottom - (
**B**) Length of Bottom - (
**h**) Height between Top and Bottom

**Trapezoid Volume Surface Area (TSA):** The calculator returns the area in square meters (m^{2}). However, this can be automatically converted to compatible units via the pull-down menu.

A rectangular trapezoid volume has regular trapezoids on all four sides with the two sets of identical trapezoids on opposite sides. The bottom and top rectangles are centered, form parallel planes and separated by the height.
