What is the total surface area of the square pyramid?

Hatshy [7]

Answer:

144 in^2

Step-by-step explanation:

There are four triangular sides to this square pyramid. According to the area-of-a-triangle formula, A = (1/2)(b)(h), which here is A = (1/2)(8 in)(5 in) = 20 in^2.

Thus, the total lateral (side) area is 4(20 in^2) = 80 in^2.

The area of the bottom is (8 in)^2, or 64 in^2.

Thus, the total surface area is 80 in^2 + 64 in^2, or 144 in^2.

Add 3 feet 6 in add 3 feet 6 in + 8 ft 2 in + 4in + 2ft 5in what does that add up to

Troyanec [42]

Answer:

173 inches

Step-by-step explanation:

i don't entirely understand the question but i think you're trying to add 3 feet 6 inches + 8 feet 2 inches + 4 inches + 2 feet 5 inches?

(3 feet 6 inches) + (8 feet 2 inches) + (4 inches) + (2 feet 5 inches)

i've added these parentheses in order to make it easier to see the grouped measurements. this isn't necessary but i'm just doing it to hopefully aid my explanation since there's so many terms in the expression!

start by converting everything to inches just to make the addition as well as showing your work easier. all you have to do is multiply the amount of feet by 12 because there are 12 inches in a foot! :)

(3 feet 6 inches) + (8 feet 2 inches) + (4 inches) + (2 feet 5 inches)

for your first measurement, 3 feet 6 inches, convert 3 feet to inches by multiplying the amount of feet, 3, by 12.

3(12) = 36 (therefore 3 feet is equal to 36 inches!)

and add the remaining 6 inches.

36 + 6 = 42 (therefore 3 feet 6 inches is equal to 42 inches!)

(3 feet 6 inches) + (8 feet 2 inches) + (4 inches) + (2 feet 5 inches)

for your second measurement, 8 feet 2 inches, convert 8 feet to inches by multiplying the amount of feet, 8, by 12.

8(12) = 96 (therefore 8 feet is equal to 96 inches!)

and add the remaining 2 inches.

96 + 2 = 98 (therefore 8 feet 2 inches is equal to 98 inches!)

(3 feet 6 inches) + (8 feet 2 inches) + (4 inches) + (2 feet 5 inches)

nothing needs to be done to this quantity since it's already in inches.

(3 feet 6 inches) + (8 feet 2 inches) + (4 inches) + (2 feet 5 inches)

for your fourth measurement, 2 feet 5 inches, convert 2 feet to inches by multiplying the amount of feet, 2, by 12.

2(12) = 24 (therefore 2 feet is equal to 24 inches!)

and add the remaining 5 inches.

24 + 5 = 29 (therefore 2 feet 5 inches is equal to 29 inches!)

now, here is the expression with everything in inches.

42 inches + 98 inches + 4 inches + 29 inches aka 42 + 98 + 4 + 29

now add everything up!

42 + 98 + 4 + 29 = 173 inches

your total is 173 inches! i hope this helps and i hope i explained it well enough. have a lovely day! <3
