Question

find the volume of a room whose Length breadth and height are 5x^y,3xy^ and 2xy units respectively​

Answer 1

Answer:

Answer

We know,

Volume of a rectangle=length×breadth×height

Given,

length,breadth, height=xy,2x

2

y,2xy

2

Therefore,

Volume of a rectangle=xy×2x

2

y×2xy

2

=4x

4

y

4

Hence option

′

D

′

is the answer.

option D is 4x⁴y⁴

Answer 2

Answer:

30x^4y^4

Step-by-step explanation:

volume of room=Length×Breadth× Height

Given,

Length=5X^2y

Breadth=3Xy^2

Height= 2XY

=5x^2y × 3xy^2 × 2XY

=15x^3y^3 × 2xy

= 30x^4y^4
