Answer:
5. 76
6. 24
Step-by-step explanation:
5.
x + x = 152
2x = 152
x = 76
6.
2x + 3x = 120
5x = 120
x = 24
To solve this question you would first multiply all the dimensions of the pillar together. That would be:
2.5 x 2.5 x 12 = 75 square feet
Then you take the weight of the pillar and divide it by the amount of square feet:
12,000 / 75 = 160 pounds per square foot.
2 triangles of 4x3/2 each. So 12.
One 3x20 rect = 60
One 4x20 rect = 80
One 5x20 rect = 100.
So total <u>252</u>
