Unformatted text preview: is a box with base A and height 3. Its volume, therefore, is given by length × width × height = (7 − 2) × (4 − 2) × 3 . Consequently, 2. I = 72 cu. units correct 3. I = 70 cu. units 4. I = 68 cu. units 5. I = 69 cu. units Explanation: The double integral I = 30 . I= f (x, y ) dxdy A keywords: volume, double integral, rectangular region, rectangular solid 002 10.0 points is the volume of the solid below the graph of f having the rectangle A= (x, y ) : 0 ≤ x ≤ 6, 0 ≤ y ≤ 4 chester (crc2876) – HW13 – meth – (91845) for its base. Thus the solid is the wedge Explanation: Since x varies but y does not, 2 z 2 x − 4 x2 y d x = I= 0 6 2 12 43 x − xy 2 3 0 . Consequently, y I = 2− 32 y. 3 (6, 4) 6 x and so its volume is the area of triangular face multiplied by the thickness of the wedge. Consequently, keywords: 004 10.0 points Determine the...
