IGCSE Grade 7 Maths Volume of cubes and cuboids
|
The volume of a cube is given by V = s³. Use this equation to find the length of an edge, and then calculate the total surface area using SA = 6s².
Volume of cuboid is Length x Breadth x Height. Here dimensions of cuboid are given in metres, but answer is asked in centimetres. So convert it likewise as, 1m= 100cm.
The volume of a cube is given by V = s³, where s represents the length of an edge.
Rearrange the formula for volume: V = l × w × h to solve for l.
Volume of cuboid is Length x Breadth x Height. Here, after finding volume of one brick, divide the total volume of the wall by volume of one brick to get number of bricks required.
The surface area of a cube is given by SA = 6s², where s represents the length of an edge.
Volume of cuboid is Length x Breadth x Height. As Volume of cuboid is given, use inverse of multiplication to find the value of breadth.
Volume of cube is (side)3.
The volume of a cuboid is given by V = l × w × h.
Volume of cuboid is Length x Breadth x Height. Here, as volume is given, use inverse of multiplication to find 'y'.
