A cube has a volume of 74 088 cm cubed. What is the surface area of the cube
Naddika [18.5K]

Answer:

10 cm²

Step-by-step explanation:

74 088 is the cubed of one side. So you would do \sqrt[3]{74088} which is 42. So one side of the cube is 42. To find the surface area, you would do 6(42x42) which would give you 10584. Remember to put cm²

Look at this triangle work out length bc​
Natali [406]

Answer:

perpendicular = 10.24 cm

Step-by-step explanation:

by pythagorus theorem,

h {}^{2}  = b {}^{2}  + h {}^{2}

( where, h = hypotenuse, b = base,

p = perpendicular )

so,

=》

13 {}^{2}  = 8 {}^{2}  + p {}^{2}

=》

169 = 64 + p {}^{2}

=》

169 - 64 = p {}^{2}

=》

p =  \sqrt{105}

perpendicular = 10.24 ( root 105 )
