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.
, where,
l = Length,
w = Width,
h = Height




Therefore, Mrs Chen needs 84 square inches of cardboard.
Answer:
Chemical
Step-by-step explanation:
Answer:
Length is 182 cm and width is 158 cm.
Step-by-step explanation:
Given:
Perimeter of rectangle table = 680 cm.
Let the width of the table be
.
Now according to given length of the table is 24 cm more than the race the width
hence length =
.
But perimeter of rectangle = 2(length+width)
Substituting the values we get;

Hence width = 158 cm
Now, length = 24 cm + width = 24 cm + 158 cm = 182 cm
Hence the dimension of table are 182 cm and 158 cm.
The answer is C! All you have to do is subtract the numbers! :) (Also, could I get brainliest?)
