Answer:
its b) 5cm^3
Step-by-step explanation:
Work Shown:
The base is a square with area 2^2 = 2*2 = 4 square cm.
V = volume of pyramid
V = (1/3)*(area of base)*(height)
V = (1/3)*(4)*(3.75)
V = 5
7x - 5y = -5 this is the standard form

Katie gets 32/8 = 4 lots of sweets
Pavel gets 4 lots x 3 = 12 sweets
First case
0.3m = r
0.3m = 18
m = 18/0.3
m = 60 mins.
Second case
0.3 x 180 = r
r = 54 rows
Third case
0.3m = 72
m = 240 minutes
Fourth case
0.3 x 360 = r
r = 108 rows
Hope this helps!
