1. Surface area of rectangular prism = 2(lb+bh+lh)
Ans = 2(3*2 + 2*4 + 3*4) = 2(6+8+12) = 52 in^2
Fourth option
2. Length of cube = x feet
Surface area = 6x²
Fourth option
3. Surface area of cylinder = πr(2h+r)
Ans = 3.14*1(2*15+1) = 97.34 cm²
second option
4. Same formula as 1
Ans = 2(10*8 + 8*12 + 10*12) = 2(80+96+120) = 592 in²
fourth option

Answer:
The grade on the fifth test that will give you a mean score of at least 85 is 87
Step-by-step explanation:
From the question, the grades on 4 math tests are 79,85,86, and 88.
To determine the grade on the fifth test that will give a mean score of at least 85,
Let the grade on the fifth test be x,
From the formula for mean
Mean = Sum of terms / Number of terms
That is,
85 = (79 + 85 + 86 + 88 + x) / 5






x = 87
Hence, the grade on the fifth test that will give you a mean score of at least 85 is 87.
