Question

Please help! Select all that apply. Write the letter of your answer. V = Iwh

Answer 1

Answer:

C.

D.

E.

Step-by-step explanation:

Formula for volume of a cuboid $= lwh$. where l is the length, w is the width and h is the height.

Using this equation we can answer the question by using the values given.

$V = (2y+4)(2y-4)(3y) = (4y^2-16)(3y) = 12y^3-48y$

From the list of answers, we can compare each one to the answer we got and see if they match up.

The answers that match up are:

C. $12y^3-48y$ - it is exactly like the answer we got.

D. $3y(4y^2-16) = 12y^3-48y$ - if we simplify the brackets, it is exactly like the answer we got.

E. $(2y+4)(6y^2-12y)=12y^3-24y^2+24y^2-48y=12y^3-48y$ - once again, if we simplify the brackets it is like the answer we got.

None of the other answers are correct as they do not match up with the answer we got.
