Frances has 4 square baking dishes. each pan is 7 inches × 7 inches × 2 inches. which expression will give her the total volume of all the pans? a. 7^2 × 2 b. 7 × 2^4 c. (7 × 2 × 2) × 4 d. (7^2 × 2) × 4

Choice D
(7^2 x 2) x 4



Each time I use "x", I mean multiply

The volume of one pan is 7 x 7 x 2 which is the same as 7^2 x 2
Multiply this by 4 and we get the total volume to be (7^2 x 2) x 4 which is what choice D shows. 

Yes you are correct
