I can't rly see the numbers,sry if i got it wrong
<span>Solution:
We have:
length = a = 3x
</span><span>width = b = x
</span>height = h = 2x
<span>area of the base of the prism = c
</span>volume of the prism = v = 2058 cm³
Use: c = (3x)(x)
c = 3x²
Use: v = (3x²)(2x)
v = 6x³
2058 = 6x³
6x³ = 2058
x³ = 2058 / 6
x³ = 343
x = ∛343
x = 7
a = 3x
a = 3(7)
a = 21
b = x
b = 7
h = 2x
h = 2(7)
h = 14
c = 3x²
c = 3(7)²
c = 3(49)
c = 147
a = 21 cm
b = 7 cm
h = 14 cm
c = 147 cm²
Answer:
4.5
Step-by-step explanation:
This problem is set up in such a way that you take 1/10 of a number and equate it to 0.45
1/10 of x = 0.45 or
1/10 * x = 0.45 Multiply both sides by 10
1/10 * x * 10 = 0.45 * 10 Combine
x = 4.5
