If x = 15 in, y = 20 in, and z = 25 in, what is the surface area of the geometric shape formed by this net?

a. 1,650 in2
b. 2,100 in2
c. 1,100 in2
d. 1,800 in2

the answer is D:  1800 square in

Step-by-step explanation:

find the area of the triangle

area = 1/2 bh

=1/2 (15 inch) (20 inch)

=150 square inch

***then multiply by 2 which gives you 300 square inch***

find the area of the 3 rectangular faces

A=lw

= (25 in) (15 in)

= 375 square inch

A = lw

= (25 in) (20 in)

= 500 square inch

A = lw

= (25 in) (25 in)

= 625 square inch

then add all 3 rectangular faces which equals to 1500 square inch

then add the triangular and rectangular

300 square inch + 1500 square inch = 1800 square inch

step-by-step explanation:

84/3.5 = 24

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24
