![]() In the advanced mode of this calculator, you can also calculate the volume of a cylinder, but we also have a dedicated tool called cylinder volume calculator. If you want to learn more about area unit conversion, check out our area converter now! With the surface area of a cylinder calculator, you can perform all the calculations in many different units. The surface area of our cardboard box is 1332in². ![]() Example 2: The perimeter of a triangular prism is 108 units and its lateral surface area is 756 units. Answer: The lateral area of the given triangular prism 160 cm 2. Thus, the lateral area of triangular prism (a + b + c ) h. Add all three rectangles areas - its equal to 666 in² ( what a number) - and finally multiply by 2. The height of the triangular prism 10 cm. First rectangle area is 15in × 12in 180in², second 15in × 18in 270in² and third one 18in × 12in 216in². Alternatively, you use the formula SA bh + (s. Calculate the rectangular prism surface area. Or total_area = 2 × π × r² + (2 × π × r) × h, This ensemble of surface area of a triangular prism printable worksheets is packed with learning Focussing on triangular prisms, this set of free pdfs requires students to find the surface area by adding up the areas of three rectangular faces and two parallel triangular bases. 2 × π × r is the circumference of the base circle,įinally, the total surface area of the cylinder formula is simply the sum of the base surface area and the lateral surface area:.Problem 6: Calculate the lateral and total surface areas of a triangular prism whose base perimeter is 25 inches, the base length and height of the triangle are 9 inches and 10 inches, and the height of the prism is 14 inches. Because the area of a rectangle is the product of its sides, we can write that: Hence, the surface area of the given prism is 489.9 sq. But remember that every cylinder has two bases! Thus, you need to multiply it by two:Įstimation of the lateral surface area is even easier. To calculate the base surface area, you need to compute the area of a circle with the radius r. Now that we know how to find the surface area of a cylinder let's derive appropriate formulas for the surface area of a right circular cylinder.
