Answer:

35 bricks for $25.90

230 bricks for $170.2

Step-by-step explanation:

Cost per brick = number of bricks / price of bricks

1500/$1110 = $1.35

1300 / $845 = $1.54

230 / $170.20 = $1.35

100 / $75 = $1.33

35 / $25.90 = $1.35

Based on these calculations, the bricks that have the same cost per brick are :

35 bricks for $25.90

230 bricks for $170.20

Hey<3 If you help you’re amazing if you don’t you’re awesome.

<h3>Answer: 576 </h3>

============================================================

Check out the diagram below.

I've split the figure into 3 separate blocks. We calculate the volume of each block, then add up those volumes to get the final answer.

Block A = largest block on the left
Block B = middle block
Block C = smallest block on the right

So,

volume of block A = length*width*height = 6*6*8 = 288 ft^3
volume of block B = length*width*height = 6*6*5 = 180 ft^3
volume of block C = length*width*height = 6*6*3 = 108 ft^3

Therefore, the total volume we're working with is:

A+B+C = 288+180+108 = 576 cubic feet

The "cubic feet" or "ft^3" portion is already taken care of by your teacher, so you just need to type in the number itself.
