A company makes gift boxes in different sizes following the pattern shown below. What is the volume of the fourth gift box to th
AVprozaik [17]

The volume of the fourth box is of 410.1 cubic inches.

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

The volume of a rectangular prism is given by the <u>base area multiplied by the height,</u> that is:

V = A_bh

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

  • For the first three boxes, the height is constant at 9 inches.
  • At the base, the <u>edge length is multiplied by 1.5</u> each time, as \frac{4.5}{3} = \frac{3}{2} = 1.5, thus, for the fourth box, the edge length, in inches, will be of 4.5 \times 1.5 = 6.75

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

  • Square base, of<u> length 6.75 inches</u>, thus:

A_b = 6.75^2 = 45.5625

  • Height of <u>9 inches</u>, thus h = 9 and:

V = A_bh = 45.5625(9) = 410.1

The volume of the fourth gift box will be of 410.1 cubic inches.

Sveta_85 [38]

Answer:

1/10

Step-by-step explanation:

add 2/5 and 1/2 then subtract from 1 whole to find the remainder

make it so they have the same denominator

2/5 = 4/10

1/2 = 5/10

4/10 + 5/10 = 9/10

1=10/10

10/10-9/10 = 1/10

so 1/10 of the students don't exercise at all
