Answer:
544 cm²
Step-by-step explanation:
hello,
to find the tsa of a rectangular prism, you use:
tsa = 2 ( lw + lh + wh )
in this case, l = 16 cm, w = 6 cm and h = 8 cm.
knowing these informations, you can proceed with using the formula.
tsa = 2 [ ( 16*6) + ( 16*8 ) + ( 6*8) ]
= 2 [ 96 + 128 + 48 ]
= 2 ( 272 )
= 544 cm²
please try to understand how i worked this out, and do let me know if you have any questions.
have a great day! thank you!
