We know that the box is a cube, so we know that this box has 6 sides of equal area.

So if one of the sides is 8.5 inches, then since it's a square, we know all of the sides are also 8.5 inches.

So the area of one side of the box is $8.5in*8.5in=72.25in^{2}$

Then we need to multiply this by 6 to get the total surface area of the box:

$72.25in^{2}*6=433.5in^{2}$

So now we know that the total surface area of the box is C) 433.5 square inches.

To solve this question, use the Cube surface area formula

Area = 6a^2 in which a = edge.

edge = 8.5

Area = 6(8.5)²

Simplify. Follow PEMDAS

Area = 6(72.25)

Area = 433.5

(C) 433.5 in² is your answer

hope this helps

I need help find the volume of the composite solid use 3.14 for pi

Evgen [1.6K]

Answer:

$222.312\:\mathrm{in^3}$

Step-by-step explanation:

The composite solid consists of a cylinder and a cone. Therefore, its total volume will be the sum of the volumes of the cylinder and cone:

Volume of the cone: $\frac{1}{3}\cdot 2^2\cdot 3.14\cdot 8.1 =33.912$

Volume of the cylinder: $2^2\cdot 3.14 \cdot 15=188.4$

Thus, the total volume of the solid is:

$33.912+188.4=\boxed{222.312\:\mathrm{in^3}}$

How do you solve 2i and 2ii

natta225 [31]

Answer:

15 and 21

Step-by-step explanation:

Given the n th term formula

T = 2n + 5

To find the 5 th and 8 th terms substitute n = 5 and n = 8 into the formula

$T_{5}$ = (2 × 5) + 5 = 10 + 5 = 15

$T_{8}$ = (2 × 8) + 5 = 16 + 5 = 21

Four circles, each with a radius of 2 inches, are removed from a square. What is the remaining area of the square?

garri49 [273]

Given:

Given that the radius of the circle is 2 inches.

We need to determine the area of the remaining square.

Area of a square:

Given that each circle has a radius of 2 inches.

Then, the diameter of each circle is 4 inches.

Hence, the side length of the square is 2 × 4 = 8 inches.

The area of the square is given by

$A=s^2$

$A=8^2$

$A=64 \ in^2$

Thus, the area of the square is 64 square inches.

Area of the four circles:

The area of one circle is given by

$A=\pi r^2$

Substituting r = 2, we have;

$A=4 \pi$

Thus, the area of one circle is 4π in²

The area of 4 circles is 4 × 4π =16π in²

Hence, the area of the 4 circles is 16π in²

Area of the remaining square:

The area of the remaining square is given by

Area = Area of the square - Area of four circles.

Substituting the values, we get;

$Area = 64-16 \pi$

Thus, the area of the remaining square is (64 - 16π) in²

Hence, Option c is the correct answer.
