To find the radius, r, of a cylinder from its surface area A, you must also know the cylinder's height, h:. Substitute the height h into the surface area of a cylinder equation:. A = 2πr² + 2πrh. Bring all terms in this equation to one side to get 2πr² + 2πrh - A = 0.Note that this is a quadratic equation in terms of r.. Solve this equation using the quadratic formula to obtainSurface area = (315) + (24) Surface area = 339 square units. Therefore, the surface area of the given prism is 339 units 2. Example 3: If the volume of a triangular prism, having a length of 7 units and the height of the base triangle 4 units, is 35 units, find the length of the base of the triangle. Solution:V = (1 2 × 12 × 5)(25) = 750in3. The volume of our triangular prism is 750 cubic inches. Now onto surface area. SA = 2B + ph. First, substitute in your formulas. SA = 2(1 2bh) + (3s)h. We can use 3s for the perimeter because it is a regular triangle, or an equilateral triangle, so all the sides are the same length.Finding the volume of a triangular prism when the BASE AREA is known. Find the volume of a triangular prism given in the figure whose base area is 256 in2. Solution: As we know, Volume ( V) = Base Area × Length, here base area = 256 in 2, length = 6.5 in. ∴ V = 256 × 6.5. = 1664 in 3. Learn how to find the volume of a triangular prism ...Solution: Given, Base area = 60 cm2. Height = 7 cm. We know that, The volume for the prism equals (Base area × Height) cubic units. Therefore, V = 60 × 7 = 420. Hence, the volume of a triangular prism = 420 cm3. Example 2: Find the height of the square prism whose volume is equal to 360 cm3 and the base area is 60 cm2.Learn how to calculate the surface area of triangular prisms.Use the formula 2 x one half base times height plus length times width in order to get the surfa...Jan 18, 2024 · Calculate the rectangular prism surface area. First rectangle area is 15in × 12in = 180in², second 15in × 18in = 270in² and third one 18in × 12in = 216in². Add all three rectangles' areas - it's equal to 666 in² ( what a number!) - and finally multiply by 2. The surface area of our cardboard box is 1332in². Or save yourself some time ... .
