Answer is: a/(1/2b+1/2c)=h
a=1/2(b+c)h
a=(1/2b+1/2c)h
a/(1/2b+1/2c)=(1/2b+1/2c)b / (1/2b+1/2c)
a/(1/2b+1/2c)=h

a rectangular prism is 4 units x 2-1/2 units by 1-1/2 units. how many cubes with a side length of 1/2 unit will completely fill

d1i1m1o1n [39]

Find 2 things
1. volume of 1 cube
2. volme of rectangular prism

1. volume of a cube=side^3
side=1/2
v=1/2^3=1/8 cubic units

2. volume=legnth times widht itmes height
4
2 and 1/2
1 and 1/2

for ease, convert to improper
2 and 1/2=2+1/2=4/2+1/2=5/2
1 and 1/2=1+1/2=2/2+1/2=3/2

so
v=4/1 times 5/2 times 3/2=60/4=15

so

how many cubes does it take to fill the prism
how many cubes times volume of 1 cube=volume of prism
xcubes times 1/8unit^3=15unt^3
multiply both sides by 8/1 unit^3 to clear fraction (since 1/8 times 8/1=8/8=1)
xcubes=240

need 240 cubes to fill prism

The tile along the edge of a triangular community pool needs to be replaced. Which expression represents the total perimeter of

topjm [15]

The total perimeter of the pool edge $\boxed{12{x^2} + 15}$ .Option A is correct.

Further Explanation:

The formula of area of square can be expressed as follows,

${\text{Area}} = \dfrac{1}{2} \times \left( b \right) \times \left( h \right)$

The formula of perimeter of the triangle can be expressed as follows,

$\boxed{{\text{Perimeter}} = 3 \times s}$

Here, s represents the side of square.

Given:

The options are as follows,

A. ${12x^2} + 15$

B. ${20x^2} + 25$

C. ${12x^2} + 8x +25$

D. ${24x^2} + 16x + 50$

Explanation:

Option A is ${12x^2} + 15.$

12 and 15 are the multiple of 3.

$\begin{aligned}{\text{Perimeter}} &= 12{x^2} + 15\\&= 3\left( {4{x^2} + 5} \right)\\\end{aligned}$

Therefore, the perimeter of the pool is ${12x^2} + 15.$

The total perimeter of the pool edge $\boxed{12{x^2} + 15}$ .Option A is correct.

Option A is correct.

Option B is not correct.

Option C is not correct.

Option D is not correct.
