Answer:
8 pens
Step-by-step explanation:
<h2><u>Finding the number of pens bought </u></h2>
pencil costs 0.27
pen costs 0.32
6 * pencils + x pens = 4.18
6 * 0.27 + x * 0.32 = 4.18
1.62 + 0.32x = 4.18
0.32x = 4.18 - 1.62
0.32x = 2.56
x = 2.56/0.32
x = 8
<u>hence 8 pens were bought </u>
Answer:
Step-by-step explanation:
l = 4m = 400 cm
w = 3m = 300 cm
Volume = 720000 cubic cm = 720000
length * width * height = 720000
400 * 300 * height = 720000
height = 720000 / 400 * 300 = 72/12 = 6 cm
