Answer:
222.7 cm³ of paper to wrap this.
Step-by-step explanation:
The rectangular prism is SA=2(wl+hl+hw)
Where:
w=5 l=5 h=4
SA= 2((5*5)+(4*5)+(4*5))
SA=2(25+20+20)
SA=2(65)=130cm³
The square base pyramid is
≈92.69578 cm³
Add the two together 130+92.70 =222.7 cm³
Given length of a lap = 5/8 mile.
Number of laps Carin ran = 3 1/2 laps.
3 1/2 can be read as 3 and a half. In improper fractions, it can be written as
(3*2+1)/2 = 7/2 laps.
In order to find the total distance covered in 3 1/2 or 7/2 laps, we need to multiply length of a lap by total number of laps ran.
Therefore, total distance covered = 7/2 × 5/8.
=
Multiplying across, we get
=
=
Let us convert 35/16 into mixed fractions.
On dividing 35 by 16, we get 2 quotient and 3 remainder.
So, the mixed fraction would be 2 3/16.
Therefore, she ran 2 3/16 miles in 3 1/2 laps.
