What is the Edge length of a cube if the surface area is 96cm2?
surface area of a cube x = length of edge surface area of 1 face is "x squared" written (x^2) a cube has 6 surfaces, total surface area = 6(x^2) 96cm2 = 6(x^2) solve for x
A cube of 5cm side, find it total surface area?
Surface area= 6x² where x = 5cm 6×5² 6×25 =150cm²
How many flat and curved surfaces does a cube have?
a cube has 0 curved faces and 6 straight face
What is the volume of the total surface area of a cube is 864 cm sq?
Total surface area = 864 cm2Area of each face = 1/6 of that = 144 cm2Length of the side of the cube = sqrt(144) = 12 cmVolume = 123 = 1,728 cm3
How many triangles of different size and shape can be formed using the vertices of a cube?
Consider a "unit cube", with all edges equal to 1 inch in length. Eight vertices - A, B, C, D, clockwise around the top, E, F, G, H on the bottom, with A directly above E, B directly above F, etc. Triangle Type 1 is completely confined to one face of the cube. The second and third points are adjacent (connected by an edge of the cube) to the first, but are opposite each other, but still on the same face. Two of the sides are edges of the cube, and therefore have a length of 1 inch. The third side is a diagonal drawn across one face of the cube, and has a length of √2 inches. This is a right triangle, and is also an isosceles triangle (the two sides adjacent to the right angle have the same length). The area of this triangle is 1/2 square inch. A typical triangle of this type is ABC. Triangle Type 2 has two vertices that are adjacent to each other (on the same edge of the cube), but the third point is the opposite vertex of the cube from the first point, and is the opposite vertex on the same face as the second point. One side is an edge of the cube and has a length of 1. The second side is a diagonal drawn across one face of the cube, and has a length of √2. The third side is a diagonal drawn between opposite vertices of the cube, and has a length of √3. This is also a right triangle, but not an isosoceles triangle, and therefore different from the first type. The area of this triangle is √2/2. A typical triangle of this type is ABG. Triangle Type 3 has three vertices that are opposite each other along the same face (though on three different faces). I.e., Vertices 1 and 2 are opposite each other along one face, 2 and 3 are opposite each other along another face, and 1 and 3 are opposite each other along a third face. All three sides have a length of √2. This is an equilateral triangle. The area of this triangle is √3/2. A typical triangle of this type is ACF.
