Answer: $2549
<u>Step-by-step explanation:</u>
A = P(1 + r)ˣ ; where P is Principal, r is rate, and x is time
Given:
- P = 1509
- r = 6% = 0.06
- x = 9
A = 1509(1 + 0.06)⁹
= 1509(1.06)⁹
= 1509(1.6895)
= 2549.42

Answer:
(c) 144 m²
Step-by-step explanation:
The surface area can be calculated from ...
SA = 2(LW +H(L+W))
SA = 2((6 m)(6 m) +(3 m)(6 m +6 m))
= 2(36 m² +(3 m)(12 m)) = 2(36 m² +36 m²) = 2(72 m²)
SA = 144 m²

<em>Additional comment</em>
The units of area are square meters (m²). The units of volume are cubic meters (m³).
A cube has 6 sides.
A cube is all made up of squares.
So, we need to find the area of one cube and multiply that by 6.
Length * width= area
40*40= 1,600
Multiply that by 6.
1,600*6= 9600
Whatever the unit is after that: in, feet, cm, m, etc- put that after the number with ^2.
9,600 (the unit) ^2
I hope this helps!
