Total surface area = 2*(128 + 83 + 3*12) = 312 square inches.
The surface area depends on the shape and you have given no indication as to what hat might be.
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
The surface area is 2*(8*11 + 11*3 + 3*8) square inches = 2*(88 + 33 + 24) sq inches = 290 square inches.
(3.14....) x (3^2)x(8) = 226.19
The surface area is 24 square units.
Entire surface area = (2*pi*42)+(8*pi*12) = 402.124 square units rounded to 3 decimal places
The curved surface area is 301.6 units2
Surface area = 2*(12*8 + 8*9 + 9*12) sq cm = 2*(96 + 72 + 108) = 552 cm2
The surface area is 552.92 units2
A rectangular box that is 6 by 8 by 12 units has a surface area of 2 x (6 x 8) + 2 x (6 x 12) + 2 x (8 x 12) = 432 square units
The surface area depends on the shape and you have given no indication as to what hat might be.
12 × 8 × 9.6 = 921.6ft3 (921.6 cubic feet).* * * * *That is the volume! The surface area is2*(12*8 + 8*9.6 + 9.6*12) = 576 square feet.

Assuming that the box is a rectangular parallelepiped, it has two sides each with dimensions 2*3, 2*4, and 3*4, with areas of 6, 8, and 12 square inches respectively. The total surface area therefore is 2(6 + 8 + 12) = 52 square inches.

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.
