The first one plez i can’t figure it out i’m freaking

Well this is how you would do it:

It is a square sandbox, meaning it is 7*7*7, but she only wand the sand to be 2 feet high, so you would remove 5 ft from the box's height. The new volume would be 7*7*2

So the amount of sand would be equal to the new volume!

Therefore she would need to order 98 ft^3 of sand

I hope I helped!

7*7*2 which is 98ft three

1. isolate the variable, in this case, d. subtract 35.5 on both sides of the equation.2. 52 subtracted by 35.5 is 16.53. therefore your answer would be d= 16.5this is the basics of pre algebra, isolating variable through adding, subtracting, multiplying, and dividing, if you have any other questions to ask just comment!
