Question

What’s the surface area

Answer 1

6x8 = 48
48 divided by 2 = 24
24 x 2 (there’s 2 triangles) = 48.

12x10 = 120
120 x 2 = 240 (theres 2)

12 x 6 = 72

72 + 48 + 240
= 360

the surface area is 360

Answer 2

$\text{Find the surface area:}\\\\\text{Area of triangle:}\,\frac{1}{2}bh\\\\\frac{1}{2}(6)(8)\\\\\frac{1}{2}(48)\\\\24\\\\\text{There are two sides with triangles, so multiply it by 2}\\\\24*2=48\\\\\text{Area of a rectangle:}\,b*h\\\\6*12=72\\\\12*10=120\\\\12*8=96\\\\\text{Add all of your values:}\\\\48+72+120+96=336\\\\\boxed{336\,\, in^2}$
