Answer:
428 square inches
Step-by-step explanation:
Hi, to answer this question we have to apply the next formula:
Surface area of a prism: 2wl +2lh+2hw
Where w is the width of the prism; l the length; and h the height.
Replacing with the values given:
S (smaller prism) = 2 (4x6) + 2(6x2)+ 2(2x4)=48+24+16= 88 in2
S (larger prism) = 2 (8x10) +2 (10 x5)+2(5x8)= 160+100+80=340in2
Adding both surface areas:
88+340 =428 in2
Feel free to ask for more if needed or if you did not understand something.
