Calculate the total surface area and lateral surface area of a rectangular prism (box). Enter length, width, and height.

Total Surface Area: 62.00
Lateral Surface Area: 32.00
Base Area: 15.00
Volume: 30.00

Formulas: TSA = 2(lw + lh + wh). LSA = 2h(l + w). Volume = lwh.

Prism Surface Area

The surface area of a prism is the sum of the areas of all faces. Total surface area includes all faces; lateral area excludes the bases .
