A designer is creating various open-top boxes by cutting four equally-sized squares from the corners of a standard sheet of 8.5
Oxana [17]

Answer:

L(x) = 11 - 2x

W(x) = 8.5 - 2x

V(x) = 4x³ - 39x² + 93.5x

Step-by-step explanation:

If a square of x sides length is cut from each corner of the sheet, then it meas the length and width of the box a shortened by x inces from each side, giving a total subtraction of 2 times x inches.

FORMULA FOR LENGTH:

Since, Length is the bigger side of the box. Therefore, it will be taken on 11 inches side of the paper:

<u>L(x) = 11 - 2x</u>

FORMULA FOR WIDTH:

Since, width is the smaller side of the box. Therefore, it will be taken on 8.5 inches side of the paper:

<u>W(x) = 8.5 - 2x </u>

FORMULA FOR VOLUME:

Volume is the product of length, width and time:

V(x) = L(x)*W(x)*H(x)

Height must be equal to the side folds which are equal to length of the side of square = x:

H(x) = x

Therefore,

V(x) = (11 - 2x)(8.5 - 2x)(x)

V(x) = (93.5 -22x -17x + 4x²)(x)

<u>V(x) = 4x³ - 39x² + 93.5x</u>

Answer:

35

Step-by-step explanation:

Maneesha: 75 % × 37 sunflower seeds equals to 27.75

27.75 is a decimal so rounded off they become 28

her friend: 1/3 × 21 = 7 pumpkin seeds
