Q5) I make a a lot of careless mistake

Q6) careless

# data[].attributes.body
Q1) I got it wrong because I forgot to put the pie beside 196
I will learn from this by being more careful and double checking my work

Q3c) I got it wrong because I didn’t take the two middle positions add them together and divide them by 2

Q4a,b,c) I got it wrong as I used the wrong height and tried to find base area when it was already given and I forgot to cube root
I will learn from this by practicing questions that are similar to this

Q5a,b,c) I got it wrong as I forgot the formula for c.s.a and used the wrong number for Pythagoras therym and used the wrong formula to find the volume
