Answer:

132.5 cm²

Step-by-step explanation:

A cuboid has 3 pairs of identical faces.

So the surface area is 2(L×W) + 2(L×H) + 2(W×H)

the calculation is 34.5 + 75 + 23 = 132.5 cm²

Can someone please help mee.<br><br> use transformations to solve the equation.<br><br> 3 2/3x = 22

gizmo_the_mogwai [7]

1. Note that

$3\dfrac{2}{3}=\dfrac{3\cdot 3+2}{3}=\dfrac{9+2}{3}=\dfrac{11}{3}.$

2. Then the equation $3\dfrac{2}{3}x=22$ can be rewritten

$\dfrac{11}{3}x=22.$

3. Solve it:

$x=22:\dfrac{11}{3},\\ \\x=22\cdot \dfrac{3}{11}=2\cdot 3=6.$

Answer: x=6
