To find the answer, all you need to do is divide 48 by 3. This shall get you the answer 16. This means that there are sixteen(16) 3s in 48.
Answer:
The length would be 5 meters
Step-by-step explanation:
To get this value, start with the area formula.
A = LW
Next input the known values for area and width
1 = L1/5
Now multiply each side by 5
5 = L
Answer:
The surface area is 91
Step-by-step explanation:
3*4=12
12/2=6
6*2=12
7*5=30
4*7=28
3*7=21
12+30+28+21=91
The equations that are on the left are caculations triangle calcuations. The equations on the right are the ones that equal each of the 2d shapes in the prism and if u add them all up you get your surface area.
