Answer:
The base area is 3.24 dm^3
Step-by-step explanation:
Let the total volume of the cube be x l
3/4 of this is 4.374 l
Thus, we have it that;
3/4 * x = 4.374
3x = 4 * 4.374
x = (4 * 4.374)/3
x = 5.832 L
The volume of a cube is the length of its side raised to the power of 3
Let us have the length as y
so;
y^3 = 5.832
y = cube root of 5.832
y = 1.8 dm
The area of the base is simply the side length raised to the power of 2
we have this as:
1.8 * 1.8 = 3.24 dm^2
The answer is Step 2.
The exponential equation is: 3ˣ⁺¹ = 15.
Step 1: log3ˣ⁺¹ = log15
Step 2: (x + 1) * log3 = log15
Step 3: x + 1 = log 15 / log 3
Step 4: x + 1 = 1.18 / 0.48
Step 5: x + 1 = 2.46
Step 6: x = 2.46 - 1
Step 7: x = 1.46
The volume of a cube can be expressed as
Let V = volume
Let a = side length
V = a^3
We need to solve the formula to isolate the variable a. First, we must cube root each side.
∛(V) = a. With our new formula, we plug in 64 cube inches into V.
∛(64) = a.
4 = a.
The length of one side on our cube is 4 inches.
