Answer:
B 10 cm by 15 cm
Step-by-step explanation:
The volume of a pyramid is given by ...
V = 1/3Bh
where B is the area of the base, and h is the height.
Solving for B, we find ...
3V/h = B
3(1000)/20 = B = 150
The product of the base dimensions must be 150 cm².
The choices are ...
A 10×5 = 50
B 10×15 = 150 . . . . could be
C 30×0.5 = 15
D 30×11 = 330
10 cm by 15 cm could be the dimensions of the vase base.
