Multiplication of length means expanding in dimension (whatever that means)
that is 1 cm x 1 cm = 1 cm^2 it's 2 dimention, so it's area of a 1 by one rectangle.
1 cm x 1 cm x 1 cm = 1 cm ^3 which is a cube, it's 3D
DO NOT try to visualize the following
1 cm x 1 cm x 1 cm x 1 cm = 1 cm^4, it's a 4D model (no one knows what it looks like)
so in your case, 2 cm x 3 cm x 2 cm= (2 x 3 x 2) cm ^3 = 12 cm ^3 (paper form is cm to the power of 3)
2*4*3= 8*3= 24 cm3
30 square centimeters
2 centimeters is just 2 centimeters, and 2 centimeters squared is 4 centimeters. 2 centimeters x 2 centimeters = 4 centimeters squared = times 2
Let the length be 2x and the width be x:- So: 2*(2x+x) = 100 => 6x = 100 => x = 100/6 => x = 16 and 2/3 cm Check: 2*(33 and 1/3 + 16 and 2/3) = 100 cm
Four square centimeters, or 4 cm^2. Simply multiply all the dimensions given: 2x2=4. 4x1=4.
2*4*3= 8*3= 24 cm3
2 cm x 4 cm x 3 cm = 24cm3
Volume = 2*4*3 = 24 cc
30 square centimeters
3cm * 2cm * 1.5cm = 9cm3
1x1x1
2 x (8 + 3) ie 22cm
2 cm x 2 cm x 2 cm = 8 cm3
9 cubic centimeters = 9 milliliters
24 cm^2 = area
2 cm x 2 cm x 2 cm
8 cm3
