Answer 1

V = 1/3 × la × t = 1280
= 1/3 × s^2 × 15 = 1280
= s^2 × 5 = 1280
= s^2 = 1280/5 = 256
= s = \|256 = 16
LP = 2 × a × £ + s x s
LP = 2 × 16 × \|1/2s^2 + t^2 + 16 × 16
LP = 32 × \|8^2 + 15^2 + 256
LP = 32 × \|225 + 64 + 256
LP = 32 × \|289 + 256
LP = 32 × 17 + 256
LP = 544 + 256
LP = 800 cm^2
