Formulas

Trapezoid area: A = ((b1 + b2) / 2) x h

Lateral area: LA = perimeter x prism depth

Total surface area: TSA = LA + 2A

Volume: V = A x prism depth

Example: b1 = 8, b2 = 5, legs 3 and 3, trapezoid height 2.4, depth 10

Base area: ((8 + 5) / 2) x 2.4 = 15.6

Perimeter: 8 + 5 + 3 + 3 = 19

Lateral area: 19 x 10 = 190

Volume: 15.6 x 10 = 156
