Answer:
volume of the square pyramid is:
V = s2h/3
where s=side length and h= height
for square pyramid A
h(a)= 8in and s(a)=12in
volume of square pyramid for A =
V(a)=s2(a) h(a)/3
V(a)=122 . 8/3 \implies⟹ 144 . 8/3 \implies⟹ 1152/3 \implies⟹ 384 in3
for square pyramid B
h(b)=24in and s(b)=36in
volume of square pyramid for B =
V(b)=s2(b) h(b)/3
V(b)=362 . 24/3 \implies⟹ 1296 . 24/3 \implies⟹ 31104/3 \implies⟹ 10368 in3
We want to know how many times the volume of pyramid B is bigger than pyramid A :
= V(b)/V(a)
=10368/384
= 27 times

Answer:
£30
Step-by-step explanation:
Gavyn has £18 more than Alex
—› G - A = £18
—› 4u - 1u = 3u = £18
1u = £18 ÷ 3
= £6
total units = 4 + 1 = 5
5u = 5 × £6 = £30
