The surface area of the solid figures depends on the part which are visible. Exercise 12.1 is based on the Chapter 12 of class 9 Maths. All the questions in this exercise are direct applications of Mensuration. To find the surface area of joined figures, you should first need to draw a rough sketch to identify the portion which are visible and to decide which are is to be calculated.
Feedback and Suggestions
If it is given to find Total Surface Area (TSA) of a solid, we must recognize, the visible part of the solid to calculate the TSA. Do not apply directly the formula of TSA in case of solid figure (combination of two or more figure). We have modified all the solutions for academic session 2024-25, if still there is any error, please inform us to further modification. Your feedback is important tool for this website’s improvement.
