Answer:
Explanation:
A of base: l ×w =5×4=20cmsquared
Missing length of c=a+b=c
C=6+2
C=8cm
A of side 1= b×h÷2 ×2
= 5×8÷2×2
= 40 ÷2×2
=20 ×2
= 40 cm squared
A of side 2= b×h÷2×2
= 4×8÷2×2
= 32 ÷ 2 ×2
= 16 ×2
= 32cm squared
Total of pyramid is = area of base + A
off side 1 + A if side 2
=92 cm cubed
