30 + 8 = 38 desks

38 x 4 = 152 legs

If you did not add those eight desks then you will have 120 legs.

So, the amount of legs will go up by 32 if you add 8 more desks.

Answer:

a) 12cm

b) 360cm²

c) 2160cm cubed

Step-by-step explanation:

you would use Pythagoras theorem for A

so half of 18 is 9

15² - 9² = 144

the square root of 144 is 12

the height is 12cm

18 x 20 = 360cm²

csa x L

csa = b x h divide by 2

18 x 12 = 216cm²/2 = 108cm²

108xm² x 20cm = 2160cm cubed
