Find the surface area of the prism 8mm 13mm 7mm

The surface area of the prism is

Step-by-step explanation:

Given:

Length of the prism = 8mm

Width of the prism = 13mm

Height of the prism =  7mm

To Find:

The surface area of the prism = ?

Solution:

Surface area of a prism is given by

S =2 ( lw + wh + hl )

Substituting the values we get,

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
