area.
Lenght = 24in
Width = 9in
Height = 3in
---------------
SA is a function of the square of the dim's.
3^2 = 9
SA is 9 times the original.
----------------
SA = 2*(L*W + L*H + W*H)
-----
x3 --> SA = 2*(3L*3W + 3L*3H + 3W*3H)
= 9 times the original.

Formula we will be using:
(i) Volume of a rectangular prism = Length×Width×Height
----------------------------------------------------------------------------------------
Length of the original prism =5 in
Width of the original prism =3 in
Height of the original prism =2 in
Enlarged prism:
Tripling the dimension means multiplying each side length by 3.
New length = 3 times the length of the original prism =3×5=15 in
New width = 3 times the width of the original prism =3×2=6 in
New height= 3 times the height of the original prism =3×3=9 in
Volume of enlarged prism = New length×New width×New height= 15×6×9=810 in³
Answer: 810 in³
