Answer:

Volume= 216 cubic yards

Surface area: 276 square yards

Step-by-step explanation:

Find volume of rectangular prism:

V= lxwxh

V= 3x18x4

= 216 cubic yards

Find surface area:

SA= 2 x (front/back area) + 2 x (right/left area) and 2 x ( bottom/top area)

Front and Back Area:

A= l x w

A = 18 x 3

= 54 square yards

Right/ left Area:

4 x 3

= 12 square yards

Top/ Bottom Area:

18 x 4

= 72 square yards

54^2+12^2+72^2

= 108+24+144

=276 square yards

SOMEONE HELP ME WITH THIS

Alexandra [31]

Answer:

X=7 and y=6

Step-by-step explanation:

Y=-2x + 20.......eq(i)

6x-5y=12.....eq(ii)

Now, putting y= - 2x +20 in eq (ii)

6x - 5(-2x + 20)=12

6x + 10x - 100 = 12

16x=12+100

X=112 /16

X=7

Then, putting x=7 in eq (i)

Y=-2*7 +20

=-14 +20

Answer:

50 lb

Step-by-step explanation:

Before drying, the cranberries have ...

(100% -99%)(100 lb) = 1 lb

of "meat."

After drying, that represents (100% -98%) = 2% of the total weight. Then the total weight is ...

1 lb = 2%·x

x = (1 lb)/0.02 = 50 lb

The dried cranberries will weigh 50 lb.
