To know that total cost of painting, first we have to know the Surface area of the jewelry box. Find surface area of the box. Step 1 : Identify a base, and find its area and perimeter. Any pair of opposite faces can be the bases. For example, we can choose the bottom and top of the box as the bases. Find base area. B = l x w. B = 12 x 15. B ...
Problems on Surface Area and Volume formulas with solution 1. Calculate the surface area and volume of a cylinder with radius 6 cm and height 15 cm. Surface Area. 2 × π × 6 × (6 + 15) + 2 × π × 6 2 = 792π square cm. Volume. π × 6 2 × 15 = 540π cubic cm. 2. Find the surface area and volume of a cone with radius 8 cm and height 10 cm.
Tutero’s surface area question bank offers students tasks to understand and calculate the surface area of various objects. Activities include measuring and comparing surface areas, solving real-world problems involving packaging and construction, and exploring surface area through 3D modeling.
Calculate the area of each face and then add them together for the surface area of the rectangular prism. The surface area of the prism is the sum of the areas. Add each area twice, since each rectangle appears twice in the prism: 8+8+12+12+6+6=52 \, f t^2 . You can also find the surface area by multiplying each area by 2 and then adding.

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.
