Insights
- The formula for calculating the total surface area of a cuboid cartoon involves adding the areas of its length, breadth, and height, with an example yielding a total surface area of 60 units. The total surface area of the cuboid cartoon in question is found to be 15000 cm square.
- Converting measurements from centimeters to meters involves dividing by 100, such as transforming 750 cm to 7.5 meters. Additionally, the area of a circle can be calculated using the formula A = πR^2, with the radius (R) being half the diameter, as shown in an example resulting in 154 square centimeters.
