Problem 19: What is the approximate mass of a Mathematics textbook? Step 1: Provide a common approximate mass for a mathematics textbook. The mass of a typical mathematics textbook can vary, but a reasonable approximation is around 1.5 kilograms. The approximate mass of a Mathematics textbook is 1.5 \, kg. Problem 20: Wambua walked round the sketch map shown below. Find the total length he covered altogether. Step 1: Identify the lengths of all sides of the sketch map. The lengths of the sides are 30 \, m, 44 \, m, 36 \, m, and 15 \, m. Step 2: Calculate the total length by adding all the side lengths. Total length = 30 \, m + 44 \, m + 36 \, m + 15 \, m Total length = 74 \, m + 36 \, m + 15 \, m Total length = 110 \, m + 15 \, m Total length = 125 \, m The total length Wambua covered is 125 \, m. 3 done, 2 left today.
