The volume of a rectangular prism with a square base is 180 in3. Its height is 5 in. Find the length of the edge of the square b

amid [387]

Answer:

l = 6 inches

Step-by-step explanation:

We have,

The volume of a rectangular prism with a square base is $180\ in^3$ .

Height of the prism is 5 in

It is required to find the length of the edge of the square base. Let it is l.

The formula of the volume of the rectangular prism is given by :

$V=l\times b\times h$

A is area of base of prism

It has a square base, l =b

$V=l^2\times h\\\\l=\sqrt{\dfrac{V}{h}} \\\\l=\sqrt{\dfrac{180}{5}} \\\\l=6\ in$

So, the length of the edge of the square base is 6 inches.

What is the point slope of the line when slope is -4 and the given coordinates are (4,-9)

Lina20 [59]

The point-slope form of the equation of a straight line is:

$y-y_1=m(x-x_1)$

We have:

$m=-4\\(4;-9)\to x_1=4;\ y_1=-9$

Substitute:

$y-(-9)=-4(x-4)\\\\\boxed{y+9=-4(x-4)}$

Find NP from the rectangle

serious [3.7K]

The diagonals of a rectangle are equal and bisect each other.

NQ= 2×5 =10

Using Pythagoras theoram,

PQ²+NP²=NQ²

4²+ NP²= 10²

NP²= 100-16

NP²= 84

NP =√84
