Here's how to solve the problem: The solid is a right triangular prism. From the diagram: • The base is a right-angled triangle with legs 7 cm and an unknown length, and a hypotenuse of 25 cm. • The height of the prism is 10 cm. Step 1: Calculate the unknown side of the triangular base. Let the unknown side be x. Using the Pythagorean theorem for the right-angled base triangle: 7^2 + x^2 = 25^2 49 + x^2 = 625 x^2 = 625 - 49 x^2 = 576 x = sqrt(576) x = 24 cm The unknown side of the triangular base is 24 cm. Step 2: Calculate the area of the triangular base. The area of a right-angled triangle is (1)/(2) × base × height. Area of base = (1)/(2) × 7 cm × 24 cm Area of base = (1)/(2) × 168 cm^2 Area of base = 84 cm^2 Step 3: Calculate the volume of the solid. The volume of a prism is given by the formula: Volume = Area of base × Height of prism. Volume = 84 cm^2 × 10 cm Volume = 840 cm^3 The volume of the solid is 840 cm^3. Step 4: Calculate the perimeter of the triangular base. The perimeter of the base is the sum of its three sides. Perimeter of base = 7 cm + 24 cm + 25 cm Perimeter of base = 56 cm Step 5: Calculate the total surface area of the solid. The total surface area of a prism is given by the formula: Total Surface Area = 2 × Area of base + Perimeter of base × Height of prism. Total Surface Area = 2 × 84 cm^2 + 56 cm × 10 cm Total Surface Area = 168 cm^2 + 560 cm^2 Total Surface Area = 728 cm^2 The total surface area of the solid is 728 cm^2. Send me the next one 📸
