What is the surface area of that

The surface area 76.32 in^2

Step-by-step explanation:

To find the surface area of a square pyramid we have to find the area of the base and the area of the sides and add them together.

Area of the base:

Since the base is a square, all we have to do is multiply 3.6 by 3.6.

3.6 * 3.6 = 12.96

The area of the base is 12.96 in^2

Area of the sides:

Since the sides are triangles, to find the area we have to multiply the length by the height and divide by 2.

3.6 * 8.8 = 31.68

31.68/2 = 15.84

The area of one of the sides is 15.84

Surface Area:

To find the surface area we have to add the area of the base and the area of the 4 sides together.

12.96 + 4(15.84)

12.96 + 63.36 = 76.32

The surface area is 76.32 in^2

7 weeks

step-by-step explanation:

convert each fraction to the least common multiple of 20, so 3/4 = 15/20 & 1/10 = 2/20, then divide 15 by 2 and you get a little over 7, so the food will last 7 weeks.

207/8 is the right
