Answer: 76

Explanation:

The surface area is all of the area faces added together

The blue is 5*4 but I have 2 of those faces so I multiply by 2

(5*4*2)=40

The red is 4*2 but I have 2 of those faces so I multiply by 2

(4*2*2)=16

The green is 5*2 but I have 2 of those faces so I multiply by 2

(5*2*2)=20

Add those together

A=40+16+20=76
