Answer: 72 square inches
step-by-step explanation:
the equation for surface area is 2lw+2lh+2hw
breaking each of the sides down,
the length is 6 inches
the width is 2 inches
and the height is 3 inches
now substitute these into the equation
2(6)(2)+2(6)(3)+2(3)(2)
24+36+12
72 square inches

Answer: 135°
Step-by-step explanation:
