hii! i would appreciate if someone can answer this for me. i will import pictures of the question and figure, thanks,

volume is 320

area of base is 96

Step-by-step explanation:

tell me in the comment if u need an explanation

Base is a square so the area of a square is lxb or 8 x 12=96cm squared.

Volume is 1/3 x base x height so it would be 1/3 x 96 x 10=320cm cubed

I think

First, we need to multiply the expression in brackets by 4. This gives (24a-20)-(9a+1) since 6 x 4=24 and 4 x 5=20. Since we have no terms to simplify in brackets and no more multiplying or dividing, we can collect like terms. 24a-9a=15a -20-1=-21 Therefore our final expression is 15a-21
