how many square inches in a square foot? and how many square centimeters in a square meter?

Answer 1

144 square inches in a square foot (12*12).

10,000 square centimeters in a square meter (100*100).

Answer 2

when in doubt, use the following foolproof method for a conversion:

put the unit in parentheses and substitue with a conversion for that unit.

for example, how many square inches in a square foot.

since 1 ft = 12 in
1 (ft)^2 = 1 (12 in)^2 = 1*(12)^2*(in)^2

(note that both the value - 12 - AND the unit - in - were squared)

= 1*(144)*(in)^2=144in^2

and since 1 m = 100 cm use
1(m)^2 = 1*(100cm)^2 = 1 * (100)^2 * (cm)^2 =10,000cm^2

Answer 3

OK, it is your right to squander your points.

Since 1 foot is 12 inches, 1 sq. ft = 12 x 12 = 144 sq. inches

1 m = 100 cm. So, 1 x 1 m = 1sq.m = 100 x 100 = 10000 sq.cm

Answer 4

1 squre foot= 1 foot * 1foot
= 12 " * 12"
=144 sq. inches.

1 square meter=1 m*1m
= 100cm * 100 cm
=10000 sq. cm

Answer 5

12in x 12in = 144 in^2

100cm x 100cm = 10,000 cm^2

Answer 6

144 sq. in.

12x12.

10,000 sq. cm.

100x100
