Question

7. Write the expression for the volume of a cuboid whose length, breadth and height are given by
the following expressions :
| 3 3 8
(a) 5x + 3y; 4x + y; 3x - 2y
b) 11/4x*3y*3;8/7xyz;21/44y*2z*2
(c) 7x + 2y; 3x + 2y; 4x - 3y​

Answer 1

Answer:

5 ( 8) = 40, an integerIn general, for any two integersa and b, a b is also an integer. ... 43 5 =8 3 2 6;15 7 5 35 =(both the products are rational numbers)4 65 11 = . ... Example 2: Subtract 5x2 4y2 + 6y 3 from 7x2 4xy + 8y2 + 5x 3y. ... (The volume of arectangular box is given by the product of its length,breadth and height).
