Answer:
The volume of water and air inside each of the plastic ice cubes is 3000mm³
Step-by-step explanation:
This problem bothers on the mensuration of solid shapes, rectangular pyramid.
The volume of a rectangular pyramid is expressed as
V=(l*w*h)/3
Given data
Length l = 20mm
Width w= 15mm
Height h= 30mm
Substituting our given data we have
V= 20*15*30/3
V= 9000/3
V= 3000mm³
Y= 1/4x+b
-3= 1/4(-4) +b
-3= -1 +b
-2 = b
y=1/4x-2
This one is a bit more complicated but i believe the answer is -1/4
