Ответ:
A) 440.44 units³
B) similar figures
C) 1486.485 units³
Step-by-step explanation:
Volume = ⅓× base area × height
= ⅓ × 110.11 × 12 = 440.44 units³
B) he doesn't have to make calculations again because the two pyramids are similar.
If the ratio of sides is given, he can find the other volume using:
(side1/side2)³ = volume1/volume2
(2/3)³ = 440.44/volume2
Volume2 = 440.44 × 27/8
Volume2 = 1486.485 units³
