You need to wrap a present that is in the shape of a rectangle prism. The present has a length of 5 inches, a width of 4.5 inches, and a height of 3.5 inches. Find the total surface area of the present.
?

Respuesta :

Total surface area of the present=
=2*(5 in * 4.5 in)+2*(5 in * 3.5 in) + 2*(4.5 in * 3.5 in)=
=45 in² + 35 in² + 31.5 in²=111.5 in²

answer:the total surface area of the present is 111.5 in²
surface area=2(LW+LH+WH)
L=5
W=4.5
H=3.5
SA=2((5 times 4.5)+(5 times 3.5)+(4.5 times 3.5))
SA=2(22.5+17.5+15.75)
SA=2(55.75)
SA=111.5 in^2
