Answer:
Surface area is 300 in Squared
Step-by-step explanation:
2(lw + wh + hl) = rectangular Prism Formula
Length- 12
Width- 9
Height- 2
So just Substitute the values.
2( 12 x 9+ 9 x2 + 12 x 2) = ?
2(108 +18+ 24)
2 x 150
= 300
Answer:
Freddie would have walked 25 miles after 12 and a half hours.
Step-by-step explanation:
Given that Freddie is walking at a constant speed, and after 2 hours he walked 4 miles, while after 4 hours he walked 8 miles, to determine how long he walked 25 miles, the following calculation must be performed:
4/2 = Miles per hour
2 miles per hour
2X = Y
2X = 25
X = 25/2
X = 12.5
Therefore, Freddie would have walked 25 miles after 12 and a half hours.
