Problem 2 : A rectangular prism has a square base with edges measuring 8 inches each. Its volume is 768 cubic inches. a) Find the height of the prism. b) Find the surface area of the prism. Solution : a) Volume of prism = Base area x height. 768 = 8 2 x height. height = 768/64 = 12 cm. b) Surface area of prism = perimeter x height
To calculate the surface area of a solid object: 1. Identify the shape (e.g., cube, sphere, cylinder) and use its specific formula. 2. Measure the required dimensions, such as side length (cube), radius (sphere), or height and radius (cylinder). 3. Apply the formula (e.g., 6a 2 for a cube, 4πr 2 for a sphere). 4. Substitute the values into the formula and perform the calculations.
