The answer is: [D]: 105 km³ . __________________________________________ The volume of the figure shown in the drawing is: 105 km³ . _____________________________________________________ Explanation: _______________________________ To calculate the following of the figure in the drawing (rectangular prism): ____________________________________________________ Volume (V) = B * h ; B = base area; h = height = 7 km (as shown in picture given).
The base area, "B" . B = (5 km)*(3 km)=15 km² (Note: The "base" is a rectangle, with a length of 5 km and width of 3 km (as shown in picture given).
The area of rectangle = length * width = (5 km)*(3 km) = 15 km² So the volume, "V" of the figure shown in the drawing = Base area * height = (15 km²) * (7km) = 105 km³ ; → which is answer choice: [D]._______________________________________________
