Answer:
the surface area is 124
the volume is 72
Step-by-step explanation:
Hi there! :)
SA = 124 cm².
V = 72 cm³
Volume of a rectangular prism: V = l × w × h
Given:
l = 4 cm
w = 9 cm
h = 2 cm
V = 4 × 9 × 2
V = 36 × 2
Surface area: SA = 2(wl + hl + hw)
SA = 2((4 · 9) + (2 · 4) + (9 · 2))
SA = 2(36 + 8 + 18)
SA = 2(62)
Hope this helped you!
