A small cube with side length 6y is placed inside a larger cube with side length 4x^2. What is the difference in the volume of t

olasank [31]

Answer:

64x⁶ - 216y³

Step-by-step explanation:

The formula for the volume of a cube is

Vol. = l³

For the large cube,

V =(4x²)³

V = 64x⁶

For the small cube,

v =(6y)³

v = 216y³

The difference in volume is

Diff. = 64x⁶ - 216y³

Amiraneli [1.4K]

Answer:

The height h = 12.87 cm.

Step-by-step explanation:

Volume = pi r^2 h

647 = pi 4^2 h

h = 647 / 16pi

h = 12.87 cm.

The area of a rectangle gets reduced by 9 sq. units,if its length is reduced by 5 units and Breadth is increased by 3 units.If w

Scilla [17]

Let the length and breadth of the rectangle be x and y.

Area of rectangle is A = xy

Therefore, the new length will be = x-5

Therefore, the new breadth will be = y + 3

So new area will be xy-9

Now the new relation will be (x+3)(y+2)=xy+67

Cross – multiplication method–

$\dfrac{x}{{{b_1}{c_2} - {b_2}{c_1}}} =\dfrac{y}{{{a_2}{c_1} - {c_2}{a_1}}} = \dfrac{1}{{{a_1}{b_2} - {a_2}{b_1}}} || x = \dfrac{{{b_1}{c_2} - {b_2}{c_1}}}{{{a_1} {b_2} - {a_2}{b_1}}} y = \dfrac{{{a_2}{c_1} - (c_2}{a_1}}}{{{a_1}{b_2}-{a_2}{b_1}}}\\$

$\Rightarrow \dfrac{x}{{305 - ( - 18)}} =\dfrac{y}{{ - 12 - ( - 183)}} = \dfrac{1}{{9 - 10)}}\\\$

$\Rightarrow \dfrac{x}{{323}} = \dfrac{y}{{171}} = \dfrac{1}{{19}} \\\Rightarrow x = 17, y = 9 \\$

Therefore, the length is 17 and breadth is 9.
