This is easy. He first earned $11 on Saturday and then on Sunday he earned some money. We don't know how much he earned, we just know he earned some money. Let's put the expression together. A good place to start would be the $11. Let's add eleven to the expression. And because he earned some more money, it's going to be addition. So currently, the expression stands at $11 +
And because we don't know how much money he made on Sunday, x will be the variable for how much he earned. So the expression will be
11 + x
√42
6²=36
7²=49
(6 1/2)² = 42.25
√42 ≈ 6.5
THe volume of the larger box is 2.1^3 times that of the ssmaller one
So Volume larger = 24 * 2.1^3 = 222.264 cm^3
Therfore volume of the tissue paper = 222.264 - 24 = 198.264 cm^3 Answer
