Answer:
613.5 m^2
Step-by-step explanation:
The area of the base is
A = 1/2 bh
= 1/2 (10) (8.7) =43.5 m^2
We have three sides with all the same area
The area of one side is 10 * 16 = 160
3 * 160 = 480 m^2
Now to the top
We have 3 sides with the same area
The area of one side
A = 1/2 bh
A = 1/2 (10) (6)
= 30 m^2
3* 30 = 90
Add all the areas together to get the total surface area
43.5 m^2+ 480 m^2 + 90 m^2
613.5 m^2

Answer:
22 - 3 × 6 + 52 = 56
Step-by-step explanation:
To solve we must use the order of operations which is PEMDAS
P-Parenthesis
E-Exponents
M-Multiplication
D-Division
A-Addition
and S-Subtraction
Multiply
3×6 = 18
22-18+52
Add and subtract
22-18 = 4
4+52 = 46
Answer:
hope this help!!
Step-by-step explanation:
1 Divide both sides by 5.
x-3.8=22/5
2. add 3.8 to both sides.
x=22/5+3.8
4. simplify 22/5+3.8 to 41/5
x=41/5
decimal=8.2
