81+144 is 225

√252 is 15cm

b. in this question well have to use surds

an isosceles triangle had a 90 and 2x45 degree angles

we hypotenuse is 10cm

√a²+a² =10cm

√2a² is 10cm which makes

a√2 equals 10

then rearrange

a=10/√2= 5√2

the answer is 5√2

A cube with a side of 1m was sawn into cubes with a side of 1 cm and then laid in a row (in a straight line). What was the lengt
MrRissso [65]

Answer:

10 km

Step-by-step explanation:

volume of cube = s^3

1 m = 100 cm

volume = s^3 = (1 m)^3 = (100 cm)^3 = 1,000,000 cm^3

Since 1 m^3 = 1,000,000 cm^3, when you lay down the 1-cm cubes in a straight line with the edges touching, the line is 1,000,000 cm long.

1,000,000 cm = 10,000 m = 10 km
