pishuonlain [190]

Answer:

84\text{ in}^2.

Step-by-step explanation:

We have been given that  Mrs. Chen's students are making and decorating gift boxes for a nursing home. The boxes are 7 inches wide, 7 inches long, and 7 inches high. We are asked to find the amount of cardboard that is needed for each box.

We will use surface area of cuboid formula to solve our given problem.

SA=2(lw+lh+hw), where,

l = Length,

w = Width,

h = Height

SA=2(7\text{ in}\cdot7\text{ in} +7\text{ in}\cdot7\text{ in}+7\text{ in}\cdot7\text{ in})

SA=2(14\text{ in}^2+14\text{ in}^2+14\text{ in}^2)

SA=2(42\text{ in}^2)

SA=84\text{ in}^2

Therefore, Mrs Chen needs 84 square inches of cardboard.

storchak [24]

Answer: 1.2 in

Step-by-step explanation:

The pythagorean theorem states that a²+b²=c².  Thus, 0.9²+b²=1.5².

1.5²=2.25

0.9^2=0.81

0.81 + b² = 2.25

1.44 = b²

b = 1.2

Hope it helps <3 :)
