Answer:
The sum is 493.4
Step-by-step explanation:
In order to find the value of the sum, you have to apply the geometric series formula, which is:
where i is the starting point, n is the number of terms, a is the first term and r is the common ratio.
The finite geometric series converges to the expression in the right side of the equation. Therefore, you don't need to calculate all the terms. You can use the expression directly.
In this case:
a=40
b= 1.005
n=12 (because the first term is 40 and the last term is 40(1.005)^11 )
Replacing in the formula:
Solving it:
The sum is 493.4
The weight of solid clay brick is 66.465 ounces, if solid brick with a length of 8 inches, a width of 3.5 inches, and a height of 2.25 inches and the clay weighs 1.055 ounces per cubic inch.
Step-by-step explanation:
The given is,
A solid clay brick in the shape of a rectangular prism.
A length of 8 inches, a width of 3.5 inches, and a height of 2.25 inches.
The clay weighs 1.055 ounces per cubic
Step:1
Formula for volume of rectangular prism,
...................(1)
Where, w - Width of the rectangular prism
h - Height of rectangular prism
l - Length of rectangular prism
From the given,
w = 3.5 inches
h = 2.25 inches
l = 8 inches
Equation (1) becomes,
Volume, V = 63 cubic inches
Step:2
Weight of brick = Volume of brick × Weight per cubic inch
= 66.465 ounces
Weight of brick = 66.465 ounces
Result:
The weight of solid clay brick is 66.465 ounces, if solid brick with a length of 8 inches, a width of 3.5 inches, and a height of 2.25 inches and the clay weighs 1.055 ounces per cubic inch.
