Jack would need to buy 2 bags of sand.
To find the answer you first have to find the volume of the rectangular box which can be found using the formula length times width times height (remember that the numbers have to have the same unit so it would look like 3 times .5 times .2 if you convert them all the feet). the volume of the box is equal to .3
Then you could set the volume of the box equal to .15x to find how many boxes he would need. The formula would be .15x=.3
Divide by .15 to get x alone and you get 2 for the answer.
I only have the answer for 1, but !
1. The area of a parallelogram is base times height. Since the area of that rectangle is twice the area of the circle, then the area of the circle is half the base times the height. It will be half of 2πr· r. The area of the circle will be πr2
I want to help you but please make it easier to understand
Answer:
312
Step-by-step explanation:
Triangles
1/2 12 *10 = 6*10 = 60
there are two triangles meaning we have to multiply 60 by 2 = 120
Rectangle
12*16 = 192
Add the two and you have the area 120+192=312
