Answer:
14.58 m3
Step-by-step explanation:
here, breadth (b) = 4cm
length (l) = 6cm
volume (v) = 350cm3
height (h) = ??
we know, volume of cuboid=
length × breath× height
or, v = L× B × H
or, 350 = 6 × 4 × H
or, 350 = 24 × H
or, 350/25 = H
or 14.58 = H
therefore, H = 14.58cm3
R = 10a - 20
ur revenue totaled 110...so R = 110
110 = 10a - 20
110 + 20 = 10a
130 = 10a
130/10 = a
13 = a <== so u spent $13 on advertising
