Answer:
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
