What is the surface area of this right rectangular prism?
1 answer:
Answer:
32 yd^2
Step-by-step explanation:
Ignore rounded approximations (i.e. 2.66, 1.33). For all calculations, use fractions and EXACT values.
This prism has 6 surfaces:
- Front: 3 x 2.66 = 8
- Back: 3 x 2.66 = 8
- Top: 3 x 1.33 = 4
- Bottom: 3 x 1.33 = 4
- Side: 1.33 x 2.66 = 4
- Side: 1.33 x 2.66 = 4
Total SA: 8(2) + 4(4) = <u>32 yd^2</u>

Answer:
The percent equation states that the part equals the percent multiplied by the whole number.
The answer is 4
2•2•2=2x or 4
1/2p=p (1-0.2)^t
1/2=(1-0.2)^t
1/2=(0.8)^t
Log (1/2)=t×log (0.8)
T=log(1÷2)÷log(0.8)
T=3.1 years
C=(5/9)*(40-32) = (5/9)*8 = 40/9 = 4 4/9
So the right answer is C.
C) x=4 is the answer
2*4-1=7
8-1=7
