Surface area of solid cuboid 8cm 6cm 2cm
strojnjashka [21]

Answer:

152 \text{cm}^2

Step-by-step explanation:

We know that the total surface area of a cuboid is the sum of the  surface area of all six of its faces.

We also know that each opposing side has the same surface area. Thus the total surface area is equal to:

2*(8*6+8*2+6*2)\\\\=2*(48+16+12)\\=2*76\\=152(\text{cm}^2)

Suppose Johnny invests $2,745 into an account, which has been earning interest for many years and he now has a total of $39,974.
Doss [256]
A negative number in this wouldn't be applicable.
Johnny started out with $2,745 in the beginning, EARNING (This being the key word) interest each year. Therefore, he comes out with $39,974, not being a negative number. 

Hope I helped! ^-^

In your home you can make and paint 17 small planters in 5 days or 12 large planters in five days. You received an order for 50
Radda [10]

Answer:

25

Step-by-step explanation:

so you can use proportions for this. Since 17 small planters can be made in 5 days you would put 5 Days under 17 SP (Sp = small planters) Then you would do 17 times x which equals 17x and 5 times 50 which equals 250. you would then divide them by each other . 250 divided by 17 is a bunch of numbers but to shorten it you can just put 14.705 or 15 if you round it.

17sp 50

----------------- 250/17 = x =14.705

5D x

you would then do the same to the other Large planters.

12LP 24. 120/12 = x = 10

-------------

5D. x

the question is how many days to make them ALL. so you would then add 10 + 14.705 which equals 24.705. then you can round that to 25 DAYS.
