Answer:

CD = 45

Step-by-step explanation:

CE = 180

( x + 6 ) + ( 4x - 21 ) = 180

5x - 15 = 180

5x = 195

x = 39

substitute x in CD

CD = x + 6

CD = 39 + 6

CD = 45

A rectangeler prism has a volume of 72 cubic units. How many unit cubes will fill the rectangular exactly

Answers

Answer:

4608 cubes

Step-by-step explanation:

It is very important to note that:

1 cube in a Rectangular Prism has a side length of 1/4

The volume of 1 cube = (side length)³

= (1/4)³ cubic units

We are told in the above question that:

A rectangular prism has a volume of 72 cubic units.

The number of unit cubes that will fill the rectangular prism exactly is calculated as:

72 cubic units ÷ (1/4)³ cubic units

= 72 cubic units ÷ (1/64) cubic units

= (72 × 64 ) cubes

= 4608 cubes

Therefore, the number of unit cubes that will fill the rectangular prism exactly is 4608 cubes

Answer:

A = 1863

Step-by-step explanation:

There are a few ways you could do this but I will do the one I know best.

Keep in mind the area is the L(enght x W(idth) = A(rea)

There are two long rectangles if you cut off the square in the middle so find the area of those two first.

31 x 23 = 713

713 x 2 = 1426 (Did this to get the area for both of them.

Now find the area of the square.

23 x 19 = 437

The you would add them all up together to get 1426 + 437 = 1863

Hope this helps :)

Answer:

1,863

Step-by-step explanation:

ok I will try to explain my answer as easy and under standable as posable.

ok what I did is the left and right side of the building I drew two lines down the middle to crate two huge rectangles on each side and one small rectangle in the middle ok. hope you understand! if you don't click the file down below.

ok after you see the file you will under stand a lot better.

what I did is on the left and right triangle I did 31 tall and 23 wide. what you do I multiply the two numbers.

31 x 23 = 713

then the middle triangle is 23 wide and I did 31 - 12 to get the tall of the triangle since it did not give it to you so I got 19.

so I multiplied 23 by 19 and got 437.

so you adding all three triangles and I get 1,863 by

713 + 713 + 437 = 1,863

hope this helps
