Answer 1

(a) 1.25 m^3

(b) 3000 kg

Explanation:

(a) The volume of a rectangular prism is L*W*H.

So volume =
`(2(1)/(2))((3)/(4))((2)/(3))=1.25 m^3`

(b) The mass=density*volume.

So mass =
`2400 (kg)/(m^3) \cdot 1.25 m^3=3000 kg`.

Answer 2

V = 1 1/4 m³

M = 3000.0 kg

Explanation:

Volume = Length × Width × Height

2 1/2 x 3/4 x 2/3

V = 1 1/4

M= 2.5m ⋅ 0.75m ⋅ 0.666666666666m ⋅ 2400kg/m³
