You're on a roll — here's how to calculate the volume of the prism: The shape is a prism with a trapezoidal base. To find the volume, we need to calculate the area of the trapezoidal base and then multiply it by the length of the prism. Step 1: Calculate the height of the trapezoidal base. From the diagram, we can form a right-angled triangle within the trapezoid. The hypotenuse is the slanted side (5 m), and one leg is the horizontal difference between the parallel sides (implied as 4 m from the student's calculation 5^2 - 4^2). Let h_trap be the height of the trapezoid. Using the Pythagorean theorem: h_trap^2 + 4^2 = 5^2 h_trap^2 + 16 = 25 h_trap^2 = 25 - 16 h_trap^2 = 9 h_trap = sqrt(9) h_trap = 3 m Step 2: Determine the lengths of the parallel sides of the trapezoid. One parallel side (b_1) is given as 3 m. The other parallel side (b_2) is the sum of b_1 and the horizontal difference: b_2 = 3 m + 4 m = 7 m So, the parallel sides are 3 m and 7 m. Step 3: Calculate the area of the trapezoidal base (A_base). The formula for the area of a trapezoid is A = (1)/(2) (b_1 + b_2) h_trap. A_base = (1)/(2) (3 m + 7 m) × 3 m A_base = (1)/(2) (10 m) × 3 m A_base = 5 m × 3 m A_base = 15 m^2 Step 4: Calculate the volume of the prism. The formula for the volume of a prism is V = A_base × L, where L is the length of the prism. From the diagram, the length of the prism is 15 m. V = 15 m^2 × 15 m V = 225 m^3 The volume of the prism is 225 m^3. What's next?
