Answer:
183.92cm^2
Step-by-step explanation:
surface area of a rectangular prism formula: 2(wl+hl+hw)
where 9.5= length
4.2=width
and 3.8= height
(4.2*3.8)+(9.5*4.2)+(3.8*9.5)
15.96+39.9+36.1=91.96
91.96*2=183.92cm^2
hope this helps!
A. Since the ribbons come in rolls of 15, we need groups of 15 yards. Since we are told that we have 322 yards. We have to find a way to express this number into groups of 15. To do that we can simply divide. 322 /15 = 21.466... since we can’t have one fourth of a role, we have to buy a whole one to be able to get that .4. So, Quincy needs 22 roles.
B. Twice means two times something. So all you do is multiply 322( the number of yards Quincy needs) times 2 = 644. Alice needs 644 yards of ribbon.
C. All you have to do is break 285 yards into 3 groups so: 285/3= 95. So, Elena needs 95 yards of yellow, 95 yards of red, and 95 yards of blue.
