Answer:
The answer is A. The volumes are the same
Step-by-step explanation:
First you have to determine the area of the cross sections for each of them.
The area of the rectangular cross section will be:
A= 7(6)
A= 21 cm²
The area of the triangular cross section will be:
A= (7)(6)
A= 21 cm²
So, they both share the same area which Cavalieri's Principle said that if two solids of equal height have equal cross-sectional area at every level, then the volume are the same.
Answer: D
Step-by-step explanation:
48/3 = 16. On the second day she sold 16 notebooks.
16-2(she sold two more each day) = 14
16+2=18
Day 1=14
Day 2=16
Day 3=18
A = l * w
[tex]a = 2 \frac{1}{4} \times 3 \frac{2}{5} \\ a = 153/20
