Camp Oaks gets 32 boxes of orange juice and 56 boxes of apple juice. Each shelf in the cupboard can hold 8 boxes of juice. What
1 answer:
Answer:
At least 11 shelves are needed for all the juice boxes.
Step-by-step explanation:
Given that:
Boxes of orange juice = 32
Boxes of apple juice = 56
Total boxes = 32+56 = 88
As one shelf can hold 8 boxes of juice.
Number of shelves =
Number of shelves = 11
Hence,
At least 11 shelves are needed for all the juice boxes.

A pyramid is regular if its base is a regular polygon, that is a polygon with equal sides and angle measures.
(and the lateral edges of the pyramid are also equal to each other)
Thus a regular rectangular pyramid is a regular pyramid with a square base, of side length say x.
The lateral faces are equilateral triangles of side length x.
The lateral surface area is 72 cm^2, thus the area of one face is 72/4=36/2=18 cm^2.
now we need to find x. Consider the picture attached, showing one lateral face of the pyramid.
by the Pythagorean theorem:
thus,
thus:
(cm^2)
but
is exactly the base area, since the base is a square of sidelength = x cm.
So, the total surface area = base area + lateral area =
cm^2
