Answer:
A = 120 cm^2
Step-by-step explanation:
The formula for surface area of a rectangular prism is:
A = 2(area of the top) + 2(area of the front) + 2(area of one side)
Substituting the values:
A = 2(20) + 2(16) + 2(24)
First, distributing:
A = 40 + 32 + 48
Then adding, giving your final answer
A = 120 cm^2
Hope this helps you :)
Answer; c^2 = a^2 + b^2
c = 17 inches
a = 8 inches
b^2 = c^2 – a^2
b^2 = 17^2 – 8^2
b^2 = 289 – 64
b^2 = 225
b = square root of 225
b = 15 inches ≈ c.
Answer:
$107.50
Step-by-step explanation:
$3.50 = 1 STUDENT
$5.00 = 1 ADULT
TWENTY FIVE STUDENTS = $3.50 × 25 = $87.50
FOUR ADULTS (ONE TEACHER AND THREE PARENTS) = $5.00 × 4 = $20.00
TOTAL COST = $87.50 + $20.00 = $107.50
