Sagot :
Answer:
- B. 54 times
Step-by-step explanation:
Pyramid volume formula:
- V = 1/3*a²h
Find the volume of A:
- V(A) = 1/3*12²*8 = 384 in³
Find the ratio of volumes:
- V(B)/V(A) = 20736/384 = 54
Answer:
b) 54
Step-by-step explanation:
Given that,
→ b = 12 inches
→ h = 8 inches
Formula we use,
→ V = (1/3) × b² × h
Now the volume of pyramid A is,
→ (1/3) × b²× h
→ (1/3) × (12)² × 8
→ (1/3) × 144 × 8
→ 48 × 8 = 384 in³
Then the times bigger than A is,
→ x = B/A
→ x = 20736/384
→ [ x = 54 times ]
Hence, the option (b) is correct.
