2cm*5cm*3cm=30cm3The volume of the cuboid: 2*5*3 = 30 cubic cm
2 * 9 cm + 2 * 4 cm = 18 cm + 8 cm = 26 cm or 9+9+4+4=26cm
The formula for the volume of a cylinder is Pi x r^2 x height. So this cylinder's volume is Pi (2cm)^2 x 5cm = 62.83 cubic cm
Area of a triangle = (1/2) x (base) x (height) Can you handle it from there ?
length + width = 20/2 = 10 length = 7cm, width = 3cm
Volume = 2*3*4 = 24 cubic cm
A scalene triangle
12cc
For it to be a right angle triangle the 3rd side must be 5cm
1/2*4*3 = 6 square cm
the equation for area is area = length * width. area = 3cm*4cm. Area = 12cm^2
Volume = 2*1*4 = 8 cubic cm which is very small for a boy
Volume of cuboid: 5*4*2 = 40 cubic cm
Volume of box: 2*7*3 = 42 cubic cm
It is: 4*2*2 = 16 cubic cm
3cm
2cm*5cm*3cm=30cm3The volume of the cuboid: 2*5*3 = 30 cubic cm
