Answer 1

D. 184 cm2

Answer 2

You can solve this with the triangular prism formula but personally i think solving by finding the area of each face is the best

the triangles you get the area by finding half of it first, the right triangles,

3 times 4=12/2=6, however that's half the triangle so each triangle is 12 cm

that's 24 cm for the triangles

two of the rectangles are 50 cm each

while the one on the base has a height of 6, so that's 60

50+50+60+24=184
