Answer:
608 cm^2
Step-by-step explanation:
<em>Top and bottom rectangles: </em>
2(10*16)
= 2(160)
= 320
<em>Middle rectangle:</em>
(12*16)
= 192
<em>Two triangles:</em>
2((12*8)/2)
= 2(96/2)
= 96
<em>Surface area of the whole prism:</em>
320 + 192 +96
= 608
Answer:
972 in^2
Step-by-step explanation:
BOTTOM: 18^2 = 324 in^2
SIDES: (18/2) * 18 = 9 * 18 = 162 in^2 * 4 = 648 in^2
TOTAL: 324 + 648 = 972 in^2
