Readme [11.4K]3 years ago
4 0

Answer:

3000 cm³

Step-by-step explanation:

Volume = Difference of Volumes of the two pyramids

Volume, V1, of the larger pyramid with tip at L:

Base area = area of EFGH = 10²

Height = ML = 15

V2 = ⅓×(10²)×15 = 4000

Volume, V2, of the smaller pyramid with tip at L:

Base area = area of = 10²

Height = OL = OM+ML = 15+15 = 30

V1 = ⅓×(10²)×30 = 1000

Volume = V1 - V2

= 4000-1000 = 3000 cm³
