Answer:
Volume = 16 unit^3
Step-by-step explanation:
Given:
- Solid lies between planes x = 0 and x = 4.
- The diagonals rum from curves y = sqrt(x) to y = -sqrt(x)
Find:
Determine the Volume bounded.
Solution:
- First we will find the projected area of the solid on the x = 0 plane.
A(x) = 0.5*(diagonal)^2
- Since the diagonal run from y = sqrt(x) to y = -sqrt(x). We have,
A(x) = 0.5*(sqrt(x) + sqrt(x) )^2
A(x) = 0.5*(4x) = 2x
- Using the Area we will integrate int the direction of x from 0 to 4 too get the volume of the solid:
V = integral(A(x)).dx
V = integral(2*x).dx
V = x^2
- Evaluate limits 0 < x < 4:
V= 16 - 0 = 16 unit^3
This is an algebraic equation. First we have a square the width is X
The length is L=3X-2. P (perimeter is 44)
Therefore P = 2L+2X
= 2(3x-2) + 2x
= 6x - 4 + 2x
= 8x - 4
44+4=8x
x=48/8
x=6
Ans: Width is 6 metres and length is 16 metres
The volume of the tower given the side length of each block and number of blocks used is 192 cubic inches
<h3>Volume of a cube</h3>
- Number of blocks used = 24
- Side length of each cube = 2 inches
Volume of each cube = s³
= 2³
= 2 × 2 × 2
= 8 cubic inches
Volume of the tower = Number of blocks used × Volume of each cube
= 24 × 8
= 192 cubic inches
Therefore, the volume of the tower given the side length of each block and number of blocks used is 192 cubic inches
