What is the surface area of this cone? Use π ≈ 3.14, and round your answer to the nearest hundredth. 8 in 4 in square inches
The surface area of a 8in by 4 in by 2 in closed box is: 2 x (8 in x 4 in + 4 in x 2 in + 2 in x 8 in) = 112 in2
The curved surface area is 201.06 units2
Total surface area = 2*(12*8 + 8*3 + 3*12) = 312 square inches.Total surface area = 2*(12*8 + 8*3 + 3*12) = 312 square inches.Total surface area = 2*(12*8 + 8*3 + 3*12) = 312 square inches.Total surface area = 2*(12*8 + 8*3 + 3*12) = 312 square inches.
Total surface area = (2*pi*42)+(8*pi*4) = 201.062 square units rounded to 3 d.p.
What is the surface area of a box whose length is 8, width is 3, and height is 4? This box has 6 faces: two rectangular faces are 8 by 4, two rectangular faces are 4 by 3, and two rectangular faces are 8 by 3. Adding the areas of all these faces, we get the surface area of the box: 8 × 4 + 8 × 4 + 4 × 3 + 4 × 3 + 8 × 3 + 8 × 3 = 32 + 32 + 12 + 12 +24 + 24= 136 A cube is a three-dimensional figure having six matching square sides. If L is the length of one of its sides, the volume of the cube is L3 = L × L × L. A cube has six square-shaped sides. The surface area of a cube is six times the area of one of these sides What is the volume and surface are of a cube having a side-length of 2.1 cm? Its volume would be 2.1 × 2.1 × 2.1 = 9.261 cubic centimeters. Its surface area would be 6 × 2.1 × 2.1 = 26.46 square centimeters
Surface Area = 2× (8×4 + 8×1 + 4×1) = 88 yards2

It is the formula for finding the surface area of a sphere which is 4*pi*radius2
What is the surface area of this cone? Use π ≈ 3.14, and round your answer to the nearest hundredth. 8 in 4 in square inches
The surface area is 552.92 units2
The surface area of a 8in by 4 in by 2 in closed box is: 2 x (8 in x 4 in + 4 in x 2 in + 2 in x 8 in) = 112 in2
Not necessarily. Having the same volume does not mean having the same surface area. As an example, if you were to take a sphere with volume 4/3*pi*r^3, and a suface area of 4*pi*r^2, and compare it to a cube with sides 4/3, pi, and 4^3, you would find that they had a different surface area, but the same volume. Let the radius of the sphere be 2, that is r = 2. In this case the surface are of the sphere is about 50, and the surface are of the cube is about 80. So a sphere and a cube, both with a volume of about 33.51 (4/3 * pi * 8), have different surface areas.
Surface area of a rectangular prism is equal to 2LW+2LH+2HW. So for this object: 2*3*4+2*3*8+2*8*4=24+48+64=136 square inches.
The curved surface area is 201.06 units2
