To calculate the surface area that needs to be painted on the outside, you need to consider all the areas that are visible and can be painted.
Start by identifying the different surfaces of the object that need to be painted. For example, if you are considering a cube-shaped object, all six sides would need to be painted.
To calculate the surface area of a specific shape, use the appropriate formula. For example, for a cube, the formula to calculate the surface area is: SA = 6s^2, where SA is the surface area and s is the length of one side.
Add up all the surface areas of the different shapes involved in your object to obtain the total surface area that needs to be painted.
The paint needs to be painted on the outside. Calculate the surface area that needs to be painted. Hint consider the areas that need to be painted very carefully
