## anonymous one year ago which two solid figures have the same volume? a. a cone with a base of 5 cm2 and height of 10cm b. a rectangular solid with a base of 5cm2 and height of 10cm c. an oblique solid with a base of 5cm2 and a slant height of 10cm d. an oblique solid with a base of 5cm2 and a height of 10 cm

2. jim_thompson5910

do you know the formulas needed?

3. anonymous

no i do not

4. jim_thompson5910

volume of a cone $\Large V = \frac{1}{3}\pi*r^2*h$

5. jim_thompson5910

Volume of Rectangular Solid $\Large V = L*W*H$

6. jim_thompson5910

Volume of Oblique Solid $\Large V = A*H$ A = area of base H = height of solid

I was thinking it was B and D

8. jim_thompson5910

what are the volumes of each?

9. anonymous

65.45 for the cone

10. anonymous

250 for rectangular solid

11. jim_thompson5910

I'm just realizing they gave you the area of the base of the cone

12. jim_thompson5910

so Area of cone = (1/3)*(area of base)*(height) Area of cone = (1/3)*(5)*(10) Area of cone = ???

13. anonymous

16.6

14. jim_thompson5910

yeah roughly

15. anonymous

okay

16. jim_thompson5910

b. a rectangular solid with a base of 5cm2 and height of 10cm area of rectangular solid = (area of base)*(height) area of rectangular solid = (5)*(10) area of rectangular solid = ??

17. anonymous

50

18. jim_thompson5910

so yeah, it is B and D. Both have a volume of 50 cubic cm

19. jim_thompson5910

for some reason I have "area" on the left side when I meant to say volume

20. anonymous

thank you again

21. jim_thompson5910

no problem
